Add excluded or inclusive filesystems to scan

[minsis]

We have many servers with the same mounted NFS mounts and we don't want to scan this multiple times. This app should allow either multiple specified file system paths or allow you to specify an excluded filesystem path, or maybe a combination of the two.

I'd recommend just running the program multiple times for each directory you'd like to scan, it should be pretty trivial to write a bash script to automate this. I'm not sure if I'll update this anymore unless there's yet another vulnerable Log4j version lol.

Ok thanks. I'll probably just fork it and add the feature in. My situation isn't a trivial one unfortunately.

@1lann I added the feature and created a PR if you decide you want to include the feature.

I'm hardly knowable in go so hopefully what I added makes sense.
