Improve settings interpretation for F3V6, though still not exactly right.

Browse Source 
The next step will be to split parsing from mode interpretation, so that
we can at least accurately identify all of PRS1's modes. Then we can
work on mapping that to OSCAR's notion of modes, which probably then needs
to be augmented.
