feat: Add MQTT publisher and tester scripts for USDA Vision Camera System

- Implemented mqtt_publisher_test.py for manual MQTT message publishing
- Created mqtt_test.py to test MQTT message reception and display statistics
- Developed test_api_changes.py to verify API changes for camera settings and filename handling
- Added test_camera_recovery_api.py for testing camera recovery API endpoints
- Introduced test_max_fps.py to demonstrate maximum FPS capture functionality
- Implemented test_mqtt_events_api.py to test MQTT events API endpoint
- Created test_mqtt_logging.py for enhanced MQTT logging and API endpoint testing
- Added sdk_config.py for SDK initialization and configuration with error suppression
