Facilitates the creation of rtp header extension implementations that can be reused across applications. Implementations are registered into the GStreamer registry as elements (idea from GstRTSPExtension) and can be retrieved by URI or filtered manually. RTP header extensions must have the classification "Network/Extension/RTPHeader" to be considered as a RTP Header extension. Fixes: https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/777 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/748>
