Enhance camera configuration and auto-recording functionality
- Updated CameraStreamer to configure streaming settings from config.json, including manual exposure, gain, image quality, noise reduction, and color settings. - Added new methods in CameraStreamer for configuring image quality, noise reduction, color settings, and advanced settings. - Extended CameraConfig to include manual white balance RGB gains. - Improved AutoRecordingManager to handle camera status updates and ensure proper recording starts/stops based on machine state changes. - Created detailed configuration documentation for blower and conveyor cameras, outlining settings and their mappings to config.json. - Implemented a comprehensive test script for auto-recording functionality with simulated MQTT messages, verifying correct behavior on machine state changes.
