Implement a login system

[adremides]

A few days ago YT implements a control to block possible bots accessing videos. It asks to sign in in order to use their services.
For example, I usually just play some videos directly from URL like this:
pymusiclooper play --url https://www.youtube.com/watch\?v\=WbJoXos2BNc
Now I get this error message:
ERROR: [youtube] WbJoXos2BNc: Sign in to confirm you’re not a bot. This helps protect our community. Learn more

Maybe if we implement a system that reads the session cookies or something like that we can bypass this restriction.

Allowing a passthrough of yt-dlp options or even adding explicit support for a subset of the CLI options would be good in this case, since that is what PyMusicLooper uses under the hood to fetch videos.

Unfortunately I haven't had much time to work on this project due to obligations IRL, so I'm not sure when I can do this. That said, please feel free to open a PR if you'd like to contribute this feature!
