  libavformat/rtpdec_opus: Set duration field on Opus AVPacket
  
  This commit will properly set the duration field of Opus AVPackets.
  Currently, duration is set to 0 on Opus packets from the RTP demuxer.
  
  The Ogg muxer depends on the duration field to properly compute the page granule
  value. Without a proper duration, the granule will be wrong, and result in
  negative pts values in ogg files.
  
  See oggenc.c:657 (ogg_write_packet_internal)
  
  This commit calculates using the opus_duration function, which was copied
  from oggparseopus.c
  
  I moved this functionality and the existing opus extradata functionality
  (added by me in 6c24f2b) into a new rtpdec_opus.c file.

  lavf: vvc_probe: lower probe score for invalid SPS/PPS/IRAP order to avoid misdetection of mp3 as VVC
  
  The current vvc_probe function checks for SPS, PPS, and IRAP NAL units but does not enforce their detection order. This can lead to false positives when PPS or IRAP appear before SPS, causing malformed or non-compliant bitstreams to be incorrectly identified as valid VVC streams.
  
  This commit modifies the logic to use boolean flags and enforces the correct detection sequence: SPS must be detected before PPS, and PPS before IRAP. This ensures more accurate probing and prevents invalid bitstreams from being misidentified.
  
  For streams with wrong ordering a lower score is returned
