Jacob Alexander 4102512579 Adding McHCK DFU Bootloader
- 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
