[Feature request] Allow aspect ratio switching for videos that need it

[Pentaphon]

Is your feature request related to a problem? Please describe.
Sometimes, MANY videos on youtube are uploaded in a bad aspect ratio like https://www.youtube.com/channel/UCP0AsEE4luYjzk4NLtNxjpw and it would be handy to be able to view them properly by switching their aspect ratio in the player itself.

Describe the solution you'd like
A button that switches to different aspect ratios to force the video to go 4:3, 16:9, 2.35:1, etc.

Describe alternatives you've considered
Basically, the aspect ratio switching of VLC is ideal and should be looked at as a model for how players should switch aspect ratio.
