mport: Show Heinrichs Weikamp 'OSTC 4' as 'OSTC 4/5'.

Since the OSTC5 uses the same firmware as the OSTC4, there is no
expectation of incompatibilities, so having one dive computer model to
support both of these is the most economical choice.

This needs to be merged before the changes to subsurface/subsurface are
merged.
