1.6

New Godot 4.3 features supported/used:

• new TileMapLayer nodes are now supported. This includes multi-layer maps, consisting of multiple TileMapLayers - but they should be grouped under a special WFC2DLayeredTileMap node.
• non-user-editable exported properties are hidden using @export_storage (those properties are exported to make rules and related objects serializable, mostly for future rule editor support)

Exampes/demos:

• added TileMapLayer (and WFC2DLayeredTileMap) usage examples
• fixed multitile mapper example location
