I didn't end up doing the uuid matching yet.

Instead, I tried to just fix up the fairly hardcoded "pick the first
characteristic for writing, the last for reading", and make that whole
logic be a lot more flexible.

So now it actually looks at which characteristics have which
properties, and tries to do the sane thing based on that.

It still works for me Shearwater and my Suunto, and it does seem to make sense.

So maybe it now works for the Mares BlueLink. And if not, I'd really
like to see the subsurface debug log from a trial..

Dirk, I've sent you a merge request on github.
