Scubapro G2: add missed command packet logging

I did the packet logging for the received data side, but forgot to do
the same thing on the command transfer side, which makes the debug logs
a bit less useful.

Of course, it turns out that a bug in subsurface means that the logging
never gets enabled anyway even when you ask for it, so right now this
particular misfeature didn't matter.  I'm hoping Tomaz/Dirk can fix the
UI widget problem.
