6cd6a6a2c2 Fix warning '...not permit being left uninit..d'
Put SocketState initialisation logic in new. This avoids using an unsafe
and unnerving MaybeUninit::uninit().assume_init() to initialise an
array, which the compiler yells at since it causes undefined behavior.

8008870bc1 Switch panic_handler to panic_halt
Move away from panic_abort as it uses intrinsics, which is nightly only.

9df0fe406f Remove VREF in reports
Since VREF is an implementation detail, there shouldn't be a need to
include it in reports.

The ChannelState vref is removed along with it as its only use was to
save VREF measurements for later reporting.

6f0acc73b8 Update LED L3 for PID status on every cycle
Check if PID is engaged on any channel every cycle, and match the status
with LED L3.

b04a61c414 Turn off LED L3 only when all channels have no PID
Change the behaviour of LED L3 to turn off only when all channels have
PID disengaged, as opposed to when any channel disengages PID.

Otherwise, when disengaging PID on a Thermostat that has had both
channels engaged in PID, the LED would turn off, even when PID is still
engaged on the other channel.

This lets the LED better reflect the status of the Thermostat as a
whole, as it would stay on as long as PID is engaged on at least one
channel.

26ad2f0119 rewrite PID
Rewrite of PID according to https://hackmd.io/IACbwcOTSt6Adj3_F9bKuw PID implementation.

To migrate:
- TEC+/- pin polarity has to be reversed.
- Some saved settings might be wiped upon flashing of new firmware, back up settings before upgrade
- Min / Max integral parameters no longer exist
- kp, ki, kd will likely need to be retuned

The software has been tested on hardware with good temperature control stability.

7c013ff4a4 PID fixes
Flipped error calculation method to correct behavior of kP and kI terms.

Added anti integral windup to integral handling.

Changed how the i and integral term is calculated, to prevent old kI settings from affecting the current i term calculation when kI is being tuned. Especially noticable when kI is set from a non-zero value to zero.
