Sequre T55 Support (#1928)

* Add T55 to build

* Approx in T55

* Update ThermoModel.cpp

* use PT1000 lookup logic

* Handle no accelerometer

* Setup for temp reading

* Lock max temp

* No movement pin

* Compensate for heater coil resistance change

* Fix min offset for T55

* Fixup font for T55

* Update draw_profile_advanced.cpp

* Update draw_temperature_change.cpp
