    /// AVCaptureDataOutputSynchronizer synchronizes the delivery of data from multiple capture data outputs (AVCaptureVideoDataOutput, AVCaptureDepthDataOutput, AVCaptureMetadataOutput, AVCaptureAudioDataOutput) to a single delegate callback.
    ///
    ///
    /// AVCaptureDataOutputSynchronizer is initialized with an array of data outputs (AVCaptureVideoDataOutput, AVCaptureDepthDataOutput, AVCaptureMetadataOutput, or AVCaptureAudioDataOutput) from which you'd like to receive a single, synchronized delegate callback. The first output in the array acts as the primary data output and determines when the synchronized callback is delivered. When data is received for the primary data output, it is held until all other data outputs have received data with an equal or later presentation time stamp, or it has been determined that there is no data for a particular output at the primary data output's pts. Once all other outputs are ready, a single delegate callback is sent with all the data aligned with the primary data output's data. Separate delegate callbacks are sent for any other data received with presentation time stamps earlier than the next primary data output time.
    ///
    /// For instance, if you specify a video data output as your first (primary) output and a metadata output for detected faces as your second output, your data callback will not be called until there is face data ready for a video frame, or it is assured that there is no face metadata for that particular video frame.
    ///
    /// Note that the AVCaptureDataOutputSynchronizer overrides each data output's -setSampleBufferDelegate:queue:, -setDepthDataDelegate:queue:, or -setMetadataObjectsDelegate:queue: method call. -[AVCaptureVideoDataOutput alwaysDiscardsLateVideoFrames] and -[AVCaptureDepthDataOutput alwaysDiscardsLateDepthData] properties are honored.
