avcodec/jpeg2000dec: jpeg2000 has its own lowres option
jpeg2000 overrides the global lowres variable with a lowres field called reduction_factor
ffmpeg -lowres X causes the reduction_factor to be set
ffplay -lowres X causes both lowres and the reduction_factor to be set
ossfuss sets only lowres
only the ffmpeg variant works. This patch tries to make the other 2 work.
Alternative we could just error out if things are inconsistent.
More complex restructuring should be limited to the master branch
to keep this reasonably easy to backport
Fixes: out of array access
Fixes: 59672/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_JPEG2000
