Support feed fetching

[walking-octopus]

YouTube.js supports fetching recommendations, subscriptions, and trending videos. Does such a feature fit within this project's scope?
Would this project also support OAuth in the future?

I just wanted to create an issue for tracking progress for this feature.

Currently this libary is a by product of a bigger project that doesn't need OAuth integretation so currently not in the scope.
But I don't see why this couldn't be implemented in the future, tho I would need to look deeper in how state is managed.
For the feeds well trending videos can already be fetched, but shorthand function for fetching specific data could be implemented if wanted.
