dive computer subtitles for gopro videos

On a couple of dives recently, I had my own dive computer and wore my GoPro in head-mounted mode.

I thought it would be nice to have the dive computer info displayed on the GoPro video, so I hacked up https://github.com/benclifford/subsurface2srt which pulls data from subsurface and makes it into a VLC subtitles file.

One problem I have is that both the GoPro and the dive computer have manually set clocks, which can be set only to the nearest minute. So guessing a start offset between the video and the dive computer file is a bit hazy.
