[idea] Remove duplicates

Some books contain duplicate images (sometimes +10 duplicate)
With a little trickery, the Regex and the unused media deletion tool, you can delete a lot of duplicates.
But in some cases, there may be a different image in the middle, or even several duplicate images.

This is where the idea for this plugin comes from:
1) The plugin opens a wall of thumbnail displaying the images of the book (or a check-list with a preview area for quick consultation)
2) We select the images that we consider identical
3) The plugin "merges" the images (renames them with a Regex like this one below, then deletes the images that have become unused)

Thank you in advance.
