Magic Cube

Corrections for the new Pyraminx5 patterns.

We've got lots of bugfixes, some 400 new Pretty Patterns.

Bump version to 1.8.3

Update the Pyraminx5 pretty patterns.

New Megaminx & Gigaminx pretty patterns.

Convert the move format to one which can hold moves of the Megaminx and Gigaminx (in preparation for introduction of the Mega& Gigaminx Pretty Patterns)
Now we use 2 bits for the angle, 3 bits for the axis and 5 bits for the bitmap of layers. This totals 10 bits so 1024, but the whole thing will not spill over 3 digits, because in the Minxes we have total of 6 axis, not 8.

Workaround for a crash.

Correct the Redmi mesh to eliminate the visible seams.

Correct the dino mesh to eliminate the visible seams.

Correct rotations of the Cube - eliminate one cse when four consecutive rotations collapse into one or a NOP.

Correct rotations of the Pyraminx - eliminate one cse when three consecutive rotations collapse into one.
