Every now and then I run into the situation of figuring out the owner of a particular file or directory, and using java interop is a little bit clunky - my first naive implementation is something like this:

(Files/getOwner (Paths/get (java.net.URI. (str "file://" (.getCanonicalPath file))))
                (into-array LinkOption [LinkOption/NOFOLLOW_LINKS]))))

Since fs already has nice abstractions over LinkOption and Paths, it seems like a nice fit to add the higher level utilty of file-owner here as well, and end up with something like:

(fs/file-owner "/some/path/or/file")

I'm attaching a drafted PR that explains the intent: #98

Add more robust tests for owner fn (babashka#97)

Use JVM system property user.name to figure out who the process owner
is, then compare that to both the owner of the home directory and a
temporary file created in process, which both should be the process
owner.
