Add new maps and tileset for the game world

- Created room1.tmx and room1.lua for the first room in the game, including tiles, collision objects, and NPCs.
- Added room2.tmx and room2.lua for the second room, featuring tiles, collision objects, and an enemy.
- Introduced a world template to manage map transitions and layout.
- Implemented a new tileset (castle.tsx and castle.lua) for the castle theme, including tile properties and image references.
