Refactor Camera and WebCam classes for improved functionality

- Replace json config loading with local_conf module
- Add conditional imports for cv2 and skvideo with import flags
- Add queue size limit and cancel_join_thread to process_queue
- Implement WebCam class with full recording capabilities
- Add camera property setters (exposure, white balance, gain, etc.)
- Improve error handling and process cleanup in stop_rec
- Update docstrings to follow consistent formatting
- Add timeout to camera_process.join() with fallback termination
- Fix PiCamera exposure parameter (renamed from shutter_speed)
