firmware/ksupport: restore exception id order

Currently the exact ordering is compared in the `pending_priorities`
test which is not necessary and is non-deterministic. This patch only
 asserts the middle priority experiment is ran before the high priority
 experiment scheduled in the future.

 Release notes
 =============
 
-ARTIQ-9 (Unreleased)
---------------------
-
-* GUI state files are now automatically backed up upon successful loading.
-* Zotino monitoring in the dashboard now displays the values in volts.
-* afws_client now uses the "happy eyeballs" algorithm (RFC 6555) for a faster and more
-  reliable connection to the server.
-* The Zadig driver installer was added to the MSYS2 offline installer.
-* Fastino monitoring with Moninj is now supported.
-* Qt6 support.
-* Python 3.12 support.
-
-ARTIQ-8
--------
-
-Highlights:
-
-* New hardware support:
-   - Support for Shuttler, a 16-channel 125MSPS DAC card intended for ion transport.
-     Waveform generator and user API are similar to the NIST PDQ.
-   - Implemented Phaser-servo. This requires recent gateware on Phaser.
-   - Almazny v1.2 with finer RF switch control.
-   - Metlino and Sayma support has been dropped due to complications with synchronous RTIO clocking.
-   - More user LEDs are exposed to RTIO on Kasli.
-   - Implemented Phaser-MIQRO support. This requires the proprietary Phaser MIQRO gateware
-     variant from QUARTIQ.
-   - Sampler: fixed ADC MU to Volt conversion factor for Sampler v2.2+.
-     For earlier hardware versions, specify the hardware version in the device
-     database file (e.g. ``"hw_rev": "v2.1"``) to use the correct conversion factor.
-* Support for distributed DMA, where DMA is run directly on satellites for corresponding
-  RTIO events, increasing bandwidth in scenarios with heavy satellite usage.
-* Support for subkernels, where kernels are run on satellite device CPUs to offload some
-  of the processing and RTIO operations.
-* CPU (on softcore platforms) and AXI bus (on Zynq) are now clocked synchronously with the RTIO
-  clock, to facilitate implementation of local processing on DRTIO satellites, and to slightly
-  reduce RTIO latency.
-* Support for DRTIO-over-EEM, used with Shuttler.
-* Support for WRPLL low-noise clock recovery.
-* Enabled event spreading on DRTIO satellites, using high watermark for lane switching.
-* Added channel names to RTIO error messages.
-* The RTIO analyzer is now proxied by ``aqctl_coreanalyzer_proxy`` typically running on the master
-  machine, similarly to ``aqctl_moninj_proxy``.
-* GUI:
-   - Integrated waveform analyzer, removing the need for external VCD viewers such as GtkWave.
-   - Implemented Applet Request Interfaces which allow applets to modify datasets and set the
-     current values of widgets in the dashboard's experiment windows.
-   - Implemented a new ``EntryArea`` widget which allows argument entry widgets to be used in applets.
-   - The "Close all applets" command (shortcut: Ctrl-Alt-W) now ignores docked applets,
-     making it a convenient way to clean up after exploratory work without destroying a
-     carefully arranged default workspace.
-   - Hotkeys now organize experiment windows in the order they were last interacted with:
-      + CTRL+SHIFT+T tiles experiment windows
-      + CTRL+SHIFT+C cascades experiment windows
-   - By enabling the ``quickstyle`` option, ``EnumerationValue`` entry widgets can now alternatively display 
-     its choices as buttons that submit the experiment on click.
-* Datasets can now be associated with units and scale factors, and displayed accordingly in the dashboard
-  including applets, like widgets such as ``NumberValue`` already did in earlier ARTIQ versions.
-* Experiments can now request arguments interactively from the user at any time.
-* Persistent datasets are now stored in a LMDB database for improved performance.
-* Python's built-in types (such as ``float``, or ``List[...]``) can now be used in type annotations on
-  kernel functions.
-* MSYS2 packaging for Windows, which replaces Conda. Conda packages are still available to
-  support legacy installations, but may be removed in a future release.
-* Experiments can now be submitted with revisions set to a branch / tag name instead of only git hashes.
-* Grabber image input now has an optional timeout.
-* On NAR3-supported devices (Kasli-SoC, ZC706), when a Rust panic occurs, a minimal environment is started
-  where the network and ``artiq_coremgmt`` can be used. This allows the user to inspect logs, change
-  configuration options, update the firmware, and reboot the device.
-* Full Python 3.11 support.
-
-Breaking changes:
-
-* ``SimpleApplet`` now calls widget constructors with an additional ``ctl`` parameter for control
-  operations, which includes dataset operations. It can be ignored if not needed. For an example usage,
-  refer to the ``big_number.py`` applet.
-* ``SimpleApplet`` and ``TitleApplet`` now call ``data_changed`` with additional parameters. Derived applets
-  should change the function signature as below:
-
-::
-
-  # SimpleApplet
-  def data_changed(self, value, metadata, persist, mods)
-  # SimpleApplet (old version)
-  def data_changed(self, data, mods)
-  # TitleApplet
-  def data_changed(self, value, metadata, persist, mods, title)
-  # TitleApplet (old version)
-  def data_changed(self, data, mods, title)
-
-Accesses to the data argument should be replaced as below:
-
-::
-
-  data[key][0] ==> persist[key]
-  data[key][1] ==> value[key]
-
-* The ``ndecimals`` parameter in ``NumberValue`` and ``Scannable`` has been renamed to ``precision``. 
-  Parameters after and including ``scale`` in both constructors are now keyword-only.
-  Refer to the updated ``no_hardware/arguments_demo.py`` example for current usage.
-* Almazny v1.2 is incompatible with the legacy versions and is the default.
-  To use legacy versions, specify ``almazny_hw_rev`` in the JSON description.
-* kasli_generic.py has been merged into kasli.py, and the demonstration designs without JSON descriptions
-  have been removed. The base classes remain present in kasli.py to support third-party flows without
-  JSON descriptions.
-* Legacy PYON databases should be converted to LMDB with the script below:
-
-::
-
-  from sipyco import pyon
-  import lmdb
-
-  old = pyon.load_file("dataset_db.pyon")
-  new = lmdb.open("dataset_db.mdb", subdir=False, map_size=2**30)
-  with new.begin(write=True) as txn:
-    for key, value in old.items():
-      txn.put(key.encode(), pyon.encode((value, {})).encode())
-  new.close()
-
-* ``artiq.wavesynth`` has been removed.

+    (``frequency1``/``phase1`` and ``frequency2``/``phase2``) that are
+    executing and sampling at the coarse RTIO frequency. They can represent
+    frequencies within the first Nyquist zone from ``-f_rtio_coarse/2`` to

+
+    After the limiter, the data is shifted in frequency using a complex

+
+    The real/in-phase data after digital up-conversion can be offset using

+
+    The ``i_enable``/``q_enable`` switches enable emission of quadrature
+    signals for later analog quadrature mixing distinguishing upper and lower
+    sidebands and thus doubling the bandwidth. They can also be used to emit

+
