Implement AI low finger displacement layout

As described in https://youtu.be/EOaPb9wrgDY?t=471 a proposed layout for 10 fingers that minimized finger movement is proposed. This "could" be implemented in mkeyb. There is also a proposed layout for typing with 2 fingers, and 1 finger.

The layout can be found also (and tried) on: https://adumb-codes.github.io/
