Data layer introduction (#254)

Browse source 
* Active power, SOH

* Total and remaining capacity

* pre-commit, baby!

* Typo

* pre-commit wrestling

* Temp min/max

* Voltage and current

* Min/max design voltage

* BMS status, max charge/discharge, cell min/max

* BMS status cleanup

* Pre-commit, we meet again

* Cell voltages and minor fixes

* Cell number

* SOC

* Missed a spot

* Event handling moved, Wh bugs fixed, time measurements improved

* Pre-commit, old friend...

* Battery chemistry

* Update TESLA-MODEL-3-BATTERY.cpp

* Total capacity/Wh max, soem default values

* Good ol' pre-comm

* Some prio/core cleanup, docs...

* Contactor closing variables

* Max charge/discharge amps

* Data layer variable documentation

* USER_SETTINGS comments

* Charger comment

* Update datalayer.h
