This patch adds support for animated JPEG XL files in both the libjxl
decoder wrapper and a separate demuxer to properly set the timebase for it.

Changes from v1:
- Made some tweaks based on review suggestions from Anton Khirnov
 -- moved packet request inside main loop
 -- added guard against avctx->pkt_timebase being unset
 -- removed size_t remaining from persistent context, changing pkt->data instead.
 -- populate AVFrame->duration field.
- Rebased against master

Leo Izen (2):
  avcodec/libjxldec: add animated decode support
  avformat/jpegxl_anim_dec: add animated JPEG XL demuxer
