Add procedural board generation

[gilben1]

Store quadrants, grab quadrants and load / rotate

[gilben1]

Going a different route, going to pseudo generate using a seed and some rules.

Rules:

1. all targets must appear within a corner piece (|_) or in a wall perpendicular to the edge of the board
2. Robots cannot be placed starting on a target
3. seed function that determines the following:
   • number of walls protruding from edges
   • number of free floating walls in the board space
   • placement of tiles
   • placement of robots

board seed will be able to generate the same board on separate runs
