[Cin] SVT-AV1 encoding quite fast on x86_64

@Terje
If you want to give it a try, I put an appimage containing libaom
3.8.0 and svt-av1 (and the av1-svt.webm preset) in my Dropbox. If you
don't like Dropbox, ask me to put it in some file transfer you know, I
have no problem.

PS: As Phyllis said, you can try to compile it yourself, following the
instructions in the manual. I assure you it's not complicated, as I've
done it myself (just ask Andrew how hard I make him mad! :) )
