[Feature request] Introduce functionality to exclude specific filenames from analysis

[cfgnunes]

Hi there! I've been utilizing rdfind to streamline the process of identifying duplicate files within a single directory. However, I've encountered a need for more refined control over the analysis process.

Would it be possible to incorporate support for excluding files based on specific extensions using a globbing pattern or perhaps a regex?

I noticed that the solution proposed in #69 (by @bes-internal), involving the find command, doesn't adequately address the issue, especially when dealing with a substantial number of files.

I think this feature would help other users (such as @jvassev and @entrity).

Your consideration of this enhancement would greatly enhance the usability of rdfind for users with diverse file management needs. Thank you!

That would be great 👍 find/xargs solution doesn't work well with huge number of files and long paths.

I agree but this seems a duplicate of #147
