Test file produced with: $ MP4Box -add "sample.mp4#video:colr=nclc,1,1,1" -new sample_18byte_nclx_colr.mp4 And then manually changing the `nclc` bytes to `nclx`. This produces an 18-byte `colr` box with type `nclx`. The bitstream of this file does not contain HDR content, so the file itself is invalid for playback with a real decoder, but adding the box is enough to test the extractor change in this commit. (aside: MP4Box will let you pass `nclx`, but it requires 4 parameters, i.e. it requires the full_range_flag to be set, resulting in a valid 19-byte colr box) #minor-release Issue: #9332 PiperOrigin-RevId: 405842520

Provides media container extractors and related utilities. Application code will not normally need to depend on this module directly.
