ab-av1 has a switch to pass extra ffmpeg libvmaf parameters. I would really love to try out n_subsample, as --probing-rate gives near unusable results, but the VMAF switch could atleast speed up VMAF calculation at faster presets, where it matters.

See also #724.

Users of n_subsample should also know about a common quirk with values that are divisible by 2.
