How can I select an individual bookmarks folder and delete all the duplicate bookmarks in it?

Edit: MrOtherGuy was very generous and made this addon! BmBGone, github repo.

I’d like an addon where I can right click on a folder and see a context menu item to delete all the duplicate bookmarks in it. The only addons I’ve found have their own pages to scan all bookmarks for duplicates. I only want to delete duplicates in specific folders.
