'''
Wasn't satisfied with vasms macro capabilities for what I needed to do. This just generates code for the data structures
that the Blitter chip expects for each frame for each tile in the overall sit-sprite animation. It then creates an array of pointers
to each frame:

anim:
|_frame1
  |_f1_1
  |_f1_2
  ... etc
|_frame2
... etc
