Feature request: Get mix video links?

[pedrocaribe]

I've been trying to extract video links from Mixes (not playlists) from YouTube, but it seems as the page is formatted in a different way from playlists.
Would it be possible to add this functionality to scrapetube?

Ex.:

Playlist link: https://www.youtube.com/playlist?list=PLx9cYq2MA5pf3QAGDuvosf0TgtMCbmBfR
Mix link: https://www.youtube.com/watch?v=ts9H1v0Ob4o&list=RDts9H1v0Ob4o
