Refactor Seabear import

Moving the GUI independent Seabear import functionality to Subsurface
core. This will allow Robert to call it directly from download from DC.

Tested with H3 against released and daily versions of Subsurface. The
result differs somewhat, but it is actually fixing 2 bugs:
- Temperature was mis-interpreted previously
- Sample interval for a dive with 1 second interval was parsed
  incorrectly
