Refactor ROM handling and remove SharedRom singleton for improved architecture

- Eliminated the SharedRom class to enhance modularity and reduce global state management.
- Updated various classes to directly manage ROM instances, improving clarity and encapsulation.
- Added new functions for loading messages and colors from ROM, enhancing functionality.
- Refactored Canvas and Editor classes to utilize direct ROM references, streamlining interactions.
- Improved documentation and comments for better code understanding and maintainability.

 The Rom class provides methods to manipulate and access data from a ROM.
 
-Currently implemented as a singleton with SharedRom which is not great but has helped with development velocity. Potential room for improvement is to refactor the editors to take the ROM as a parameter.
