feat: Implement gRPC ROM service for remote manipulation

- Added `RomServiceImpl` class to facilitate remote ROM operations, including reading/writing ROM data, managing versions, and submitting proposals.
- Integrated gRPC support for real-time collaboration and remote access to ROM functionalities.
- Updated `README.md` to document the new gRPC ROM service and its capabilities.
- Enhanced CMake configuration to include new source files for the gRPC implementation and related services.
