Tidy up of python autogenerated messages (#1594)

This fixes mostly formatting issues so there is no longer any diff with
things after rerunning the generation script. Yes, most of this can be
fixed by running wpiformat but that doesn't exist as a pre-commit hook
atm, so I think this is nicer.

It also removes any reference to the java encode/decode within the
python message gen
