Enhancement - Skip downloading an image if the file name matches excluding the file extension

[Lagicrus]

Is it possible to add a feature or flag that would skip downloading a file if the file name to download matches a file name that already exists but ignores it if the file extension matches?
I've run into this issue recently as I've run an image optimizer/shrinker to save space, which changes the file extensions from .jpg to .avif
But when I rerun gallery-dl over the source, it starts downloading all the already downloaded files, just converted to a new file extension.

i.e. it would download test-image_1.jpg even though test-image_1.avif existed

Well, that's one way to do it, but you should seriously consider using the "archive" option.

True, but if I am not mistaken, the archive option only works if

• You've been using it from the start
• You don't delete items which would make the archive out-of-date
  That and I am not so sure it would still count for the whole "any file ext" use case
