Adding updated information on Windows Builds.

- Windows builds and loading has been working just fine
- screen does work with Cygwin, but there are output problems (echoing isn't working for basic input, commands still work)
- TeraTerm works good, but kills the serial port if you don't quit after reloading the firmware

 Rather than use a special program that can interpret Raw HID, this controller exposes a USB Serial CDC endpoint.
 This allows for you to use a generic serial terminal to debug/control the keyboard firmware (e.g. Tera Term, minicom, screen)
