files with multiple-dots extensions doesn't get removed (*.spec.js, *.test.js,...)

Hello,

We are using nm-prune to reduce the size of our lambda deployment package, and we like it.

The only problem we have, is that we can't remove ".." files. Would be handy to remove ".spec.js" and ".test.js" files.

Thank you!

Thanks @mcongy. Would you be willing to create a PR for this functionality? I would be happy to merge.
