In addition to the existing MX version with per key LEDs, added underglow with a jumper to allow using:
- Just per key LEDs
- Per key LEDs and Underglow
- Underglow only (doing this requires that you solder the jumper on the top side of the pcb, near the MCU)
In this release, I also flipped the MX switch footprints so that the per key leds are on the top side of the switch instead of the bottom. For backlit keycaps with legends on the top of the key, they light up much nicer with this version
