- Abstracted USB Module
- Abstracted compiler specific includes for Scan, Macro, Debug, and USB modules
- Updated CMake build files to support changes
- Added abstractions necessary to main.c as well as a compiler specific include file

- Fixed up basic Macro module (still not to my liking)
- Added the bootloader entry bits
- Added logic for key sequence tracking

- Includes new "table pinning" setup (much easier to understand)
- Matrix layouts will be split into their own dependent modules later
- Changed the HID Raw view id (too many teensy devices on this
  computer...)
- Moved the macro processing outside of the usb timer signal
  (this will be slower overall, but will result in more consistant
  behaviour)

- Caused by too much processing in the converter...
- Easy to fix if I remove the macro engine...

- main.c is now mostly complete
- Required fixes to matrix.c (some are temporary)

- Commenting cleaned up
- usb_keyboard_debug is not finished yet in terms of cleanup (needs DEBUB_PRINT #ifdef's)
- Added LoadFile script generation
- Formalized KeyIndex and USBKeys data containers
- Split parts of scan_loop into Macro, USB, and main.c
- Added interface to USB modules
- Added interface to Macro modules
- Added proper Debug module enable/disable
