SwiftMediaMetadata 3.0.3

Fixed

• MXF parsing now jumps over essence using the Random Index Pack (or the
  footer's PreviousPartition chain) instead of visiting every frame's KLVs.
  Frame-wrapped XAVC/XDCAM clips previously cost one small read per KLV across
  the whole file — seconds on SSD and far longer on camera cards; a 16 GB
  XAVC clip now parses in ~20 ms. Essence KLVs are also no longer peeked, and
  the NRT/ARRI fallback scan is limited to the header metadata. Files without
  a valid partition index keep the previous full walk.
• MXF picture dimensions now use the descriptor's display rectangle when it is
  smaller than the stored (coding-block padded) one, matching ffprobe. XAVC
  1080p was reported as 1920×1088 with a 136:135 pixel aspect ratio.
