--duplicates: Find duplicate files

[dd]

I'm aware there are similar tools that do this, but I'd still like this for this utility.

Usage: --duplicates FOLDER (May assume "." by default?)

On find, both full paths are printed:

* Duplicate found
1: C:\abc\file1.bin
2: C:\Users\dd\file2.bin

Honestly, that should be its own utility, and out of the scope of this one
