Add ZScreamCustomOverworld ASM v3 and integrate area size support

Browse Source 
- Introduced ZScream Custom Overworld ASM to enhance customization of the ALTTP overworld, allowing users to modify various aspects such as palettes, backgrounds, and transitions.
- Updated OverworldEditor to include area size selection for v3 support, enabling users to choose between different area sizes (Small, Large, Wide, Tall).
- Enhanced OverworldMap to load area size information based on the applied ASM version, ensuring compatibility with expanded features.
- Implemented SaveAreaSizes method in Overworld to persist area size settings in the ROM, supporting the new customization capabilities.
- Refactored related classes and methods to accommodate the new area size logic and ensure seamless integration with existing functionalities.
