Pinecil v2 tune via PID (#1827)

Browse Source 
* Start PWM after adc irq fully done

* Filter len 4

* Use comparitor 2 on timer for wrap around

* Update IRQ.cpp

* Tip measurements are uint16_t

Update BSP.cpp

Update BSP.cpp

* WiP PID

move pid tuning to config

Update PIDThread.cpp

* Handle PWM Timer gitchy comparitor

* Tuning

* Dampen with Kd

* Cleaning up

* Use TemperatureType_t for getTipTemp()

* Add small rolling average to user GUI temp to reduce flicker

* Trigger PID when adc is skipped (will use old values)
