and re-organize so that esp32 s2/s3 don't do as much at reset
.. it's not necessary (because most data is in esp-idf managed memory)
and doing this saves me from having to debug why reconstruct isn't working
properly on that platform.
This needs to be tested on other platforms again before being merged!
* Introduce explicit serpentine: bool argument instead of using negative
numbers (thanks, ghost of @tannewt sitting on one shoulder)
* Fix several calculations of height
Testing performed (matrixportal):
* set up a serpentine 64x64 virtual display with 2 64x32 tiles
* tried all 4 rotations
* looked at output of REPL
This gets all the purely internal references. Some uses of
protomatter/Protomatter/PROTOMATTER remain, as they are references
to symbols in the Protomatter C library itself.
