* initial files for rev 6 with encoder

* music map init, dip scan added

* adds ws2812 driver for arm

* flesh out dip and encoder support

* adds default encoder res

* adds default encoder res

* start muse implementation

* muse working with encoder as control

* flip direction

* try mouse wheel again

* dont break other revs

* dont break other revs

* conditional autio

* pwm ws driver (not working)

* update build includes for chibios

* update ws2812 driver/config

* last commit for glasser code

* working example

* remove rgb for now

* finish up rev6

* working encoder keycodes

* add warnings to planck keymaps about the LAYOUT
