[Feature] Add crop tool

[Sleeping-Donut]

Describe the feature

Have a crop tool in the download menu to crop the video to a certain region, the same way one might crop a photo.

Reason for adding

Currently to download a portion of the video runtime the "cut" tool can be used, however downloading a portion of the frame requires using separate applications or using the yt-dlp command directly. This would make it much more convenient especially as doing it as a command is difficult since there is no visual reference for where it is cropping.

Example(s)

Where the button can go

A crop ui
