fix: h26x packet buffer video artifacts

This change resolves an issue that arises when there is a gap in the
sequence numbers of packets associated with a single frame.

Before this change, the H26x packet buffer could potentially assemble a
frame using only a subset of the packets in the buffer if a packet was
missing in the middle and a packet with a marker bit arrived.

To address this, the change introduces a check before assembling a
frame. This ensures that all packets belonging to a single frame are
correctly collected by iterating backward until the first packet in the
frame is identified.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
