Take the CCR diluents into account

Browse Source 
The Suunto DX supports 3 CCR diluents and 8 OC gas mixes. Since the gas
mix index in the data is relative to either the set of CCR diluents or
OC gas mixes (depending on the dive mode) and libdivecomputer reports
both sets, the index needs to be adjusted.
