protomatter: Respond to review comments

 - rename oe_pin -> output_enable_pin
 - improve and reorganize docstrings
 - rename swapbuffers->refresh
 - rename "paused" -> "brightness", change semantics slightly
 - common_hal several functions
 - clarify why the common_hal routines can't be used directly in the
   protocol's function pointers
 - whitespace cleanups
 - remove prototypes for nonexistent functions
