I'll need to get my OSTC 2N and my OSTC 3 out and do a
- backup
- write random settings
- restore
- backup

cycle and check that the two backups are identical...

I am obviously rather nervous about this code. A prior instantiation ended
up getting my OSTC3 into a state (with earlier firmware, thanks to
Matthias this couldn't happen anymore with the latest version) where it no
longer calculated any deco / ndl... which is kinda the point of a dive

And of course, what's still missing is the firmware update :-)
