Smart face remap for pipped D6

[obasille]

For now we expect animations to have 21 entries:

• index 0: face 1
• index 1 to 2: face 2
• index 3 to 5: face 3
• index 6 to 9: face 4
• index 10 to 14: face 5
• index 15 to 20: face 6

The electrical <-> canonical look table need to be updated.

Example: when face 5 is remapped to face 3, light up the face just like it would be done for face 5 (but with 2 "corner" LEDs disabled so we have a 3)
