Support decoding and embedding VANC packets delivered via SMPTE 2038 into the SDI output. We leverage an intermediate queue because data packets are announced separately from video but we need to embed the data into the video frame when it is output. Note that this patch has some additional abstraction for data streams in general as opposed to just SMPTE 2038 packets. This is because subsequent patches will introduce support for other data codecs. Thanks to Marton Balint for review/feedback.
