Same directory usage

[bdelee-zz]

I was wondering if it's possible to run this on a single directory, comparing all the images inside that directory and seeing if there are any duplicates in there.

For example, I am running:

image-duplicate-remover ./images ./images

I know for a fact that there are duplicates in that directory, but it's telling me:

Total of 0 primary image files had exact "sha256" matches under the secondary directory
Total of 0 files removed

Total of 0 primary image files had exact "filesize" matches under the secondary directory
Total of 0 files removed

I could spend some time trying to extend this module to include the ability to check the same directory if only one is given, but I figured I'd check with the maintainer first to see if there is something I'm missing.

Thanks for the issue.

This topic has been touched in #12, and it is still valid.

It would be great to be able to check duplicates in one directory.

Please make PR...
