JVET-S0154 aspect9 and JVET-S0158 aspect4: bitstream extraction of extracting non-nested SEI from nested SEI

  1. JVET-S0154 #9: In the subpicture sub-bitstream extraction process, insert SEI NAL units to directly contain those SEI messages that were scalable-nested HRD-related SEI messages that apply to the output bitstream, and remove their original container SEI NAL units from the output bitstream. When the target OLS includes only one layer, apply the same for scalable-nested non-HRD-related SEI messages.
