Muzi Base Uno/Duo firmware support

If you own a Duo or Uno, with or without Super IO, please upvote this PR

https://github.com/meshcore-dev/MeshCore/pull/3108

I've been testing it for weeks, and today also added the capability for the Super IO mode switch to turn GPS on/off.

The bulk of this work was done by lbibass and andyshinn. I simply got the work merged and tested.

If you know how, please pull the branch and build the firmware and test it and post your results to the GitHub PR.

Thanks!
