BUGFIX: Skip MOD Test for CCR in Sensor modes (OSTC cR and OSTC3 only)
CHANGE: Swap positions of ppO2(O2) and ppO2(Dil) in customview 10 on screen. "left = lean" and "right = rich"
BUGFIX: A wrong configured gas was suggested as "Better gas" on the configured depth even if this resulted in a ppO2 high or low condition
