Add an option to properly hide videos which are superficially hidden in Subscriptions, either manually or automatically

[insin]

My Subscriptions page now has so many hidden videos it immediately loads a second page, so there are 125 videos on there by default:

08:25:03.900 🙋 handling https://www.youtube.com/feed/subscriptions
08:25:03.900 🙋 observing subscriptions <ytd-rich-grid-renderer> style attribute (for --ytd-rich-grid-items-per-row changing)
08:25:03.900 🙋 observing subscriptions <ytd-rich-grid-renderer> rows (for new rows being added)
08:25:04.881 🙋 observing refresh canary href
08:25:04.882 🙋 55 videos added
08:25:06.473 🙋 70 videos added

It would be nice to have an option to hide these properly using YouTube's built-in Hide functionality, so they get completely removed from Subscriptions. Perhaps we could add a control to Subscriptions similar to the "Remove watched videos" item playlists have:

Or just an option to automatically work through your hidden videos in the background while you're on the Subscriptions page. I don't know if there's rate limiting on the Hide functionality, hopefully slowly working our way through hidden videos in the background would avoid hitting that if there is one.
