- Does not output to usb yet
- USART is functionally getting characters from the keyboard and sending
beep codes and ACK request code (Baud rate properly calculated)
- Uses hard-coded keys for the PC to Keyboard commands (not desireable)
- Keyboard sends ASCII data, which makes doing things like holding
multiple keys almost impossible to detect (the board isn't NKRO
anyways, though I've found 8+ key combos that work)
