Push accesses to cached fields down into `field-cache.c` from parsers that use the field cache. As a result, all cached fields will be available to Subsurface in computer models that use the field cache. In particular this means that the proper use type (diluent / OC bailout) of tanks will be shown for the Garmin Descent dive computers once that is merged.
