youtube_dl & internal backends are obsolete

[elig0n]

youtube_dl is obsolete. yt-dlp replaced it but its backend needs to be implemented.

>>> pafy.new("https://www.youtube.com/watch?v=bMt47wvK6u0")

Internal backend looks outdated as well:

I'm really new to youtube-dl and pafy but wanted to use this for a project of mine. Seems like we need to change the backend to support yt-dlp also?

I'll look into this and see if this is something I can contribute

look around in the other issues you will find there are a few methods to adapt it to yt-dlp, i.e. link the youtube-dl binary to yt-dlp
