Pytec is a misnomer, as the Thermostat is not limited to just
controlling TEC modules. The library also interfaces with and controls
the Thermostat itself, and not the TEC module directly.

The Steinhart-Hart equation was changed in code long ago to the
B-parameter equation. Rename references to it and the interface
accordingly. The `s-h` command is now `b-p`.
The reason the name "B-Parameter" equation was chosen over
"Beta-Parameter" was due to its easier searchability.
Current limit pins are driven by PWM inputs to the MAX1968 driver, but
this is an implementation detail, and should not be exposed in the form
of the command interface. Rename "pwm" to "output" in all instances.
See #62 (comment).
Show in PwmSummary the set value, before all PWM duty calculations
instead of the machine value after the calculations. Also save the set
value into the flash store instead of the machine value.
Putting the maximum in PwmSummary has little use - the maximum never
changes throughout the runtime of the firmware and can be replaced by
documentation elsewhere.
Effectively flips all values related to the directionality of current
through the TEC, including current maximums. The reversed status is
stored in the flash store and will be loaded on reset once saved.
The command is "pwm <ch> polarity <normal/reversed>", where the "normal"
polarity is indicated by the front panel markings.
This is needed for IDC cable connections to the Sinara 5432 DAC
"Zotino", since the TEC pins of the 10-pin connector on the Thermostat
and Zotino have opposite polarities.
As the report mode command breaks the send-receive architecture model of
the command interface, and is deemed an anti-feature, making clients
difficult to write, remove it from the firmware entirely.
* Fix wrong calibration of VREF on startup. Caused new v2.2.2 boards to
wrongly calibrate the zero-point to ~2.2 V instead of 1.5 V.
* Fix bootloop on some boards.
* Adjust watchdog interval accordingly.
