A way to handle age restricted videos?

[AE720]

Is your feature request related to a problem? Please describe.

I searched around and found no mention of handling age restricted videos and was hoping there could be a solution to implement them for YouTube videos or if there's an easy way and I neglected it, to at least append to to FAQ.

Describe the solution you'd like

I was wondering how possible it would be to import cookies from YouTube to serve as that authorization to stream the video. I know many YouTube downloaders used to offer a way to add in a cookie to do just that.
