thumbnails for mp4

youtube-dl supports embedding with AtomicParsley and the --embed-thumbnail flag. Unfortunately youtube-dl is downloading the .webp version of the thumbnail and there is no way to specify it to download a .png or .jpeg.
AtomicParsley cannot use a .webp directly for embedding into an .mp4 and youtube-dl doesn't do a conversion of the .webp thumbnail into a usable format.

Current idea is to use --exec to add post processing to do it.
