Wow, what a trip this was. Layer support is now fully implemented. Other
changes here mostly revolve around the event dispatching model: more
floating state (hidden in clases wherever) has been purged, with the
reducer (now mutable, comments inline) serving, as it should, as the
sole source of truth. Thunk support has been added to our fake Redux
clone, allowing Action Creators to handle sequences of events (which is
arguably a cleaner way of handling matrix changes when not all matrix
changes should result in a new HID report - in the case of internal
keys). A whole class has been deprecated (Keymap) which only served as
another arbitor of state: instead, the MatrixScanner has been made
smarter and handles diffing internally, dispatching an Action when
needed (and allowing the reducer to parse the keymap and figure out what
key is pressed - this is the infinitely cleaner solution when layers
come into play).
- Lock our vendored dependencies (also pull in some new ones I will be
needing soon)
- Ensure we have a sane way of pulling those vendored dependencies into
the DFU-flashable images (upy-freeze.txt)
- Break up the Makefile into a bunch of smaller, sometimes reusable
chunks
- Add a noop keyboard that simply exits, so we can flash a "keyboard"
that just dumps us straight to REPL
- Remove my personal ampy config since that's not portable at all
