Added compile option for o2/diluent pressure display:
Some external devices (like the RedBare rebreather) provide pressure sensor information o2 and diluent bottles. A data channel from RTE to main CPU has been defined and a visualization has been added to the lower left corner (llc). Pressure will be displayed in the gas list as well => for o2 display the definition of a 100% o2 gas is needed. Diluent will be assigned to the first gas. The ADVANCED_GAS compile switch needs to be activated for this feature
