Making pipe-viewer compatible with the mpv sponsorblock script.

[canisllup]

So, there is this script https://github.com/po5/mpv_sponsorblock which works really well when you use mpv <youtube_link> or with ytfzf, but not with pipe-viewer. I think the reason is because of the name of the file that pipe-viewer grabs and it's not recognized by the sponsorblock script. Any ideas how we could make this work? Either on pipe-viewers side or on the script? Of course one way to fix this would be by using youtube-viewer, but I'd rather stick with pipe.
