nice nano zmk fw

[funkycode]

hey, I made Klein ZMK repo for nicenano - might be useful for someone. I assume it is possible to have 2 options in same repo, but not sure how to achieve it.

P.S.: Few notes for future improvements:

1. seems like with nicenano there is barely any place for screen
2. I would suggest to have more pins for touchpad (I think azoteq tp43s is exact dimensions to fit keyboard, and I assume RDY and maybe RST pins would be useful)
3. if it is possible to move encoder a little bit so it would be possible to use 1.5 or even 2u for outter thumb cluster buttons
4. i would suggest to use little bit bigger on/off switch and reset buttone (like on corne wireless) as those were pain to solder manually
