[Keyboard] Add Orbit keyboard (#5306)

* Get things working except indicators

* Attempt to get things working

* hmm

* Compiles but doesn't run

* Make data transfer work

* Get all indicators working

* Remove old transport

* Prepare for pullreq

* Revert keymap from testing to production

* Final error checking for pull request

* Remove autogenerated is_command from config.h

* Rewrite pin toggles using qmk functions
