New features:
- Mappers now can define initial WFC rules. For
TilemapLayermaps, rules can now be inferred from tilesets terrain settings (as suggested in #24), see example. But it currently works with square tilemaps only yet. Adding support for other shapes and layouts shouldn't be difficult. - Added a "remap" precondition for 2D WFC, which covers the use-case discussed in #26. See the example.
