Support for 64x32

[raymiec]

Would be sweet, it almost works in 32x32, some lines are off.

but full use of the matrix would be nice.

Hi @raymiec,

please also have a look at the https://github.com/toblum/TetrisAnimation repo. It's a improved version as a library. Brian has also a video on it: https://www.youtube.com/watch?v=2IejVgrSlWE He used it on a 64x32 matrix.
