Use Oxygen Sensor Reset Relay to Reset O2 Sensor on Loss of Signal

[allpowerlabs]

On loss of O2 signal (0V, as currently available) reset O2 relay. Set Lambda State machine in new Mode that stops updating PID until return of signal (see PID lib. for instructions on disabling PID computation)

O2 Relay reset when O2 signal hits threshold. PID set to smoothed value until the O2 reading comes back at which point it goes back into normal operation.
