fix: address LGPE encounter data PR feedback

- Rename rare-spawn to special-spawn encounter method
- Remove 44 LGPE-specific location areas and remap encounters to existing RBY/FRLG areas
- Duplicate encounters for multi-floor dungeons (Mt Moon, Pokemon Tower, Pokemon Mansion, Cerulean Cave)
- Delete invalid Cerulean Cave b3f/b4f encounters (floors don't exist in LGPE)
- Add tests job to GitHub Actions workflow
