Adding adc2 & new temperature calibration proceedures. [WiP] (#361)

* Add rough calls to ADC2 [untested]

* Using dual ADC injected modes

* Start both ADCs

* Move some IRQ's to ram exec

* Stabilize PID a bit more

* Add in ideas for tip type selection

* Add tiptype formula / settings struct

* Add function ids to the settings menu

* Rough tip selection

* Rough out new cal routine for simple tips

* Hardware test is fairly close for first pass

* Add Simple calibration case [UNTESTED]

This adds the calibration option that uses boiling water to the calibration menu.

This is untested, and may need gain adjustments before use.

* Simple Cal Roughly working

* Rough out advanced cal
