Use the HP CCR data for the oxygen/diluent usage

Browse Source 
For dives in HP CCR mode, the oxygen and diluent tanks are stored at a
fixed index. This information is more reliable than using the tank name,
and also prevents the incorrect labeling of one of the other tanks as an
oxygen or diluent tank.
