Subproject to accomodate second half pad built in opposite orientation (places TRRS jacks on opposing edges for shorter cable runs)
* Moved duplicated defines out of inappropriate source files (matrix pins in keymap subdirectory) * Eliminated default keymap directory * Hardcoded serial keymap to use serial defines and EE_CONFIG * Hardcoded i2c keymap to use i2c defines
Having a dedicated I2C keymap and a dedicated serial keymap will allow the testing suite to check both conditions.
