WIP: W.I.P.: Release/new state machines
Seperate the breathing loop finite state machine into two seperate ones.
- BreatheFSM
- FillFSM
Also seperate the function to control the valves (setValves). One for air-,O2- and purge-valve (setFillValves) and the other for inhale- and exhale-valve (setBreatheValves).
