Wipes AVC parameter sets ( SPS/PPS ) from the packet

@param in
AVC frame encoded in Annex B NAL unit format
@param out
Buffer where packet without PS will be put
@param spsList
Storage for leading SPS structures ( can be null, then all
leading SPSs are discarded ).
@param ppsList
Storage for leading PPS structures ( can be null, then all
leading PPSs are discarded ).
