This allows this common H.274 SEI to be parsed from both H.264 as well as HEVC, as well as probably from VVC in the future. Generally attempts to keep the original code as similar as possible. FATE test refererence changes only change the order of side data export within a single frame. Nothing else seems to have changed.
