Osmo360 support

[thisisbommy]

You recently added Action 6 support, which I'm very grateful for.

I wondered if you'd be interested in adding Osmo 360 support? This shoots MP4s in single lens mode, and OSVs in 360 mode.

Looking at the files, they both appear to store the GPS info in the same way, at the end of the file. pyosmogps currently reports the MP4 as being from an unknown camera and can't process the OSV.

Here's an OSV and an MP4, and the headers and tails I generated from them.

Hello. I've just realised that my MP4 in that folder has no GPS data. I can supply another later in the week if you're interested!
