- Fix logic bug in ext power detect after runin discharge. Machines turning off runin discharge could fail to sense external power.
- Print ACR value and SOC when going into stop mode
- Refactor critical and low flag handling to fix corner cases. There were several corner cases where you could get the previous code to display the wrong LED state.
- Add support for GP LiFePO4 batteries. There are few around the Twine offices.
- Turn off battery state debugs in LiFePO4 code

Ver: 7 0.3.06
- 0.3.06
- Change battery over temperature indicator to be a pulse of dark (both LEDs off) rather than a pulse of red. Red is now exclusively for errors.
