Redirect any /watch?v= or /shorts/ URL to a customizable other URL (/embed/ by default).
The redirect removes all URL params except start time and playlist. This means, playlists will continue playing (and with no delay inbetween).
You can choose to redirect shorts and normal videos to different URLs.
Hidden options:
Append #stay to any YouTube watch URL to prevent the redirect (once). This is the same mechanism which allows you to click any link inside of the embeded video to go back to the original page.
