DennyTom's buttery_engine (#8138)

* Selectively adding pieces

* Adding georgi keymap

* Adding more files, fixing make

* Smaller makefiles

* Fixing make rules

* README more inline with QMK's guidelines

* Turning off buggy assert

* Improving documentation based on a user feedback.

* Slightly better schema

* Resurrected state machine diagram
