    co2_sensor: Handle pre-calibration by states · a5e847e9

    * split state PREPARECALIBRATION into
    PREPARECALIBRATION_INSTABLE (co2 measurements are changing
    too much to start calibration) and
    
    PREPARECALIBRATION_STABLE (co2 measurements are stable,
    now waiting for 60 stable measurements)
    
    * Handle all possible LED signal states in showState()
    * drop now unused `waiting_color`
