Xudes' Youtube Extension wót xudes

I got tired of having 2 extensions packed with features for this that take up unnecessary resources so I decided to make a simple version of it on my own.

Scrollwheel: adjusts the volume per 1%, non-adjustable, might change in the future.
Shorts navigation: simply allows you to skip forward/backward in a short.

*NOTE*
This will probably only receive any update once it stops working for me which can either be earlier or later then it would for you!
