Menu cleanup rebreather specific settings: In the previous version the selection for Fix setpoint or sensor was in the deco menu and the Fallback option in the hardware menu. As they have a dependency and are only relevant for rebreather operation, they have been moved into the extra menu which is containing rebreather related data and which is only visible in rebreather mode.
