David Nadlinger 3f0cf6e683 runtime: Stop kernel CPU before restarting comms CPU on panic 
Before, the system would enter a boot loop when a panic occurred
while the kernel CPU was active (and panic_reset == 1), as
kernel::start() for the startup kernel would panic.

David Nadlinger 7955b63b00 master: Always write results to HDF5 once run stage is reached 
Previously, a significant risk of losing experimental results would
be associated with long-running experiments, as any stray exceptions
while run()ing the experiment – for instance, due to infrequent
network glitches or hardware reliability issue – would cause no
HDF5 file to be written. This was especially troublesome as long
experiments would suffer from a higher probability of unanticipated
failures, while at the same time being more costly to re-take in
terms of wall-clock time.

Unanticipated uncaught exceptions like that were enough of an issue
that several Oxford codebases had come up with their own half-baked
mitigation strategies, from swallowing all exceptions in run() by
convention, to always broadcasting all results to uniquely named
datasets such that the partial results could be recovered and written
to HDF5 by manually run recovery experiments.

This commit addresses the problem at its source, changing the worker
behaviour such that an HDF5 file is always written as soon as run()
starts.

ad9910: fix asf range (#1450) 
* ad9910: fix asf range

The ASF is a 14-bit word. The highest possible value is 0x3fff, not
0x3ffe. `int(round(1.0 * 0x3fff)) == 0x3fff`.

I don't remember and understand why this was 0x3ffe since the beginning.
0x3fff was already used as a default in `set_mu()`

ad53xx improvements (#1445) 
* ad53xx: voltage_to_mu() validation & documentation (closes #1443, #1444)

Robert Jördens ea79ba4622 ttl_serdes: detect edges on short pulses 
Edges on pulses shorter than the RTIO period were missed because the
reference sample and the last sample of the serdes word are the same.

This change enables detection of edges on pulses as short as the
serdes UI (and shorter as long as the pulse still hits a serdes sample
aperture).

In any RTIO period, only the leading event corresponding to the first
edge with slope according to sensitivity is registerd. If the channel is
sensitive to both rising and falling edges and if the pulse is contained
within an RTIO period, or if it is sensitive only to one edge slope and
there are multiple pulses in an RTIO period, only the leading event is
seen. Thus this possibility of lost events is still there. Only the
conditions under which loss occurs are reduced.

In testing with the kasli-ptb6 variant, this also improves resource
usage (a couple hundred LUT) and timing (0.1 ns WNS).
