New revision for PouetPouet board

What is changing:
 - Cherry-MX hotswap sockets for all 60 switches
 - Per switch RGB LED (SK6812-MiniE)

What is not changing:
 - Size (exact same board cutout)
 - overall components (mcu stmf072)

Even if these are small changes, I had to reroute everything, so the pcb has
been remade from scratch. The electrial schema has been kept really close to
initial version.

This should match the version sent to manufacturing, but you can really check
the aisler-order-220612 tag (should be the same files, only git history has
been cleaned/squashed).
