Expanded keyboard firmware

[hasn0life]

I added some functionality to the keyboard firmware, I figured I'd link it here in case you or other people want to take from it or add to it. Thanks! https://github.com/hasn0life/t-deck-keyboard-ex/tree/main

Hello hasn0life, it is very cool. A more "blackberry look and feel" with key holding would be perfect but it would break API (single byte per key).

@hasn0life does that mean I could control the keyboard backlight by just using #define keyboard_BL_PIN 9? is that documented anywhere else?
