[proposal] Refactor/qmk arsenik generator

[severindupouy]

I made this refactor of the qmk script for my personal use, maybe it could fit other people usage.

My goals was :

• remove the editor opening during script. I found it more annoying than useful.
• I used to re-flash many times with different options, I wanted a script to facilitate to re-run and control generated files
• I found useful to rely directly on qmk cli, as it offers many features
• separate generation and copy, as sometimes I want to do only generate or only copy
• add logs about what script does
