feat(youtube): set channel specific default video playback speed

[avichou]

Application

YouTube

Issue

There are channels whose content is really slow and can be sped up (lessons, courses, psychology stuff etc) , at 1.75* speed for example

On the other hand, most other videos play well at 1* speed ..

Patch

Would be handy to have the settings being remember on a per channel basis , so of i watch stuff from Jordan Peterson channel for example, it uses the last speed i used for it , 1.75* lets say

And leave any other channel/video at regular speed (be it 1* regular .....or default speed as per revanced settings )

Motivation

It would allow for slow videos to be sped up without impacting other kind of content

Something to model after would be what this browser script has: can "save" the current speed for the channel as well as define speed buttons to be on the video overlay (as requested on #1620).
