* Subclass Process for audio_process * Introduce custom mp.Process subclass In preparation to switch the multiprocessing startup method away from "fork", we cannot rely on os.fork cloning the log state at fork time. Instead, we have to set up logging before we run the business logic of each process. * Make camera_metrics into a class * Make ptz_metrics into a class * Fixed PtzMotionEstimator.ptz_metrics type annotation * Removed pointless variables * Do not start audio processor when no audio cameras are configured
