Prototype support clone cells in computational grid generation (python)

[GolnesaK]

For the prototype / dev version, we treat all obstacles as cutlines. In a later stage, we may either introduce a new layer in the schematisation (clone_cell_cutline) or add a boolean attribute to the obstacle layer (is_clone_cell_cutline).

Implement the following in threedigrid-builder:

• cut the cells into clone cells w/ the cutlines

  • "snap to pixel grid" the cutlines -> Rasterize

• rasterize the cells ids into a raster ("area mask")

  • minimum 1 pixels per clone cell domain
