At this point I no longer consider this patchset to be "WIP" so feel free
to take a look without another version arriving unless I receive some
requested changes.

Changes:
v6:
- some cosmetic changes
- check the AVFrame metadata if AVCodecContext's is missing
v5:
- fix attaching ICCP even if an enum can
  accurately describe the colorspace
v4:
- fix a typo. bluh
v3:
- some cosmetic changes
- properly handle P3 spaces
- properly handle PQ transfer
v2:
- avoid misusing AVMasteringDisplayMetadata
- ignore custom primaries in header (very rare without iccp)

Leo Izen (2):
  avcodec/libjxldec: properly tag output colorspace
  avcodec/libjxlenc: properly read input colorspace
