Helper function for partial pressure calculation

Browse source 
This patch introduces a new structure holding partial pressures (doubles in bar) for
all three gases and a helper function to compute them from gasmix (which holds fractions)
and ambient pressure. Currentlty this works for OC and CCR, to be extended later to PSCR.

Currently the dive_comp_type argument is unused.
