This change introduces physics layer (collision filtering) capabilities to TileMaps in AdaEngine.
Key changes include:
1. **`TileMapLayer` Enhancement:**
- Added a `collisionFilter: CollisionFilter` property to `TileMapLayer`, allowing each layer to define its own collision category and mask.
2. **`TileMapSystem` Update:**
- The system now applies the `collisionFilter` from the `TileMapLayer` to the `Collision2DComponent` of individual tile entities when they are created.
3. **LDtk Integration:**
- `Ldtk.TileMap` can now parse physics layer information from custom properties in LDtk layer definitions.
- It expects integer custom properties named `physicsLayer_categoryBitMask` and `physicsLayer_collisionBitMask` on layers.
- These values are used to configure the `collisionFilter` on the corresponding `TileMapLayer`.
4. **Testing:**
- Added a new test suite `TileMapPhysicsTests` with comprehensive tests for various collision scenarios involving TileMap layers and external entities, verifying the correct behavior of category and mask bits.
5. **Example Scene:**
- Created a new example scene `scene_tilemap_physics_app`.
- This scene demonstrates how to set up different physics layers in a TileMap (ground, obstacles, collectibles) and how a player entity interacts with them based on their collision filters.
This feature allows for more granular control over physics interactions in tile-based levels, enabling developers to create more complex and robust game mechanics.
