Move to ZMK module for the keyboard, add Studio

This commit moves the config repository to build from a ZMK module.
This allows the developer of the keyboard to add/tweak features without
the users having to pull changes - they can just re-build their firmware
and enjoy all the latest features.
As an example - this commit adds ZMK studio support with all the
necessary physical layout work done in the module.
