Please add support for Subsurface dive log exports

[rikv-1]

Super nice app!

1. Have you looked into importing Subsurface exports (CSV)? (https://github.com/subsurface/subsurface)
   As a scubadiver I use subsurface to manage my dive logs and export log data from there.
   I had to massage the log to create a csv that Depthviz can parse, it'd be great if Depthviz could read the subsurface exports.
   (Subsurface can import data from many divecomputes, so this would also make Depthviz usable with more divecomputers)

2. For subadivers it'd be nice to have more details in addition to the depth. e.g. temperature, tank-pressure, etc.
