There's a bug when converting APNG files to WEBP files, which
imagemagick delegates to ffmpeg. When doing 'nix build' and running the
result, or running pict-rs in the dev shell, it works fine. In the
container, this doesn't work at all. imagemagick complains that there's
no media to convert, implying ffmpeg has output a zero-sized file.
This work is helping to narrow down exactly what pict-rs needs to run,
though. This still needs to be tested against h264, h265, vp8, vp9 and
av1.
Remove default security policy, since it is overridden anyway
Update default value for max_area
Inherit animation frame count configuration for list-length
