[feature request] Process many files in one run

[lastrosade]

Say we have a directory with 100+ videos that could be split in 2 to 4 parts and we have 32 workers.

It would be neat if av1an could just scan them all one after the other and slowly add new chunks to the worker queue.

This would allow a major speedup.

In order to select settings per video, we could provide scripts to av1an. For example For example "-ff script.ps1" with:

#!/bin/pwsh
param($path)

if ([int](mediainfo --Output="Video;%Height%" "$path") -ge [int](mediainfo --Output="Video;%Width%" "$path")) {
    echo = "-vf 'scale=min(1080\,ih):-1:flags=sinc'"
} else {
    echo = "-vf 'scale=-1:min(1080\,iw):flags=sinc'"
}

Here, av1an would run the script on every videos in the directory to get the desired settings.

Could this work around the issues we discussed before?
