feat: Refactor Emulator to Accept ROM Parameter and Enhance Logging

- Updated Emulator::Run method to accept a Rom* parameter, improving flexibility in ROM handling.
- Refactored texture creation and ROM data initialization to utilize the new parameter.
- Enhanced logging in Snes class to provide detailed information during initialization, reset, and frame processing, aiding in debugging and performance monitoring.
- Introduced cycle tracking in Apu and Spc700 classes for accurate synchronization and debugging.
- Added unit tests for APU DSP functionality and IPL ROM handshake to ensure reliability and correctness of audio processing.
