Functionally no different, just a better user experience.

- mk20dx128vlf5 doesn't have enough bootloader space left
- Downloads the entire firmware flash (not the bootloader)
- Currently no intelligence built-in to determine full size of firmware (tricky, and sometimes not useful)

Use a consistent standard - Tabs in front for indenting, spaces after for anything else. This way everything stays nice and lined up while also letting users change there prefered indent level. Most of the new files from Haata where already in this format.

- Heavily modified, not compatible with McHCK images
- Uses 4k of Flash (rather than 3k)
- LED turns on when in firmware flash mode
- Changed the USB IDs
- Added CMake build system
- Updated linker script to be closer to what is used for the rest of the projects
- Removed a lot of unnecessary code
- Added a license header to each file (using the same license as the McHCK had)
- Updated the USB Vendor, Product and Serial strings
- Using the Kiibohd initialization sequence rather than the McHCK one
- Using Kiibohd interrupt vector table and other misc mk20dx setup
