In some situations, the checker might run outside of the context of a repository/code base, just checking files that are directly passed as arguments. In these cases, it would we cool to specify the path to a file that contains the .editorconfig config via CLI flag.

Example:

editorconfig-checker -editor-config /some/path/.editorconfig /tmp/some-temporary.file

So here the .editorconfig isn't in a parent dir of the file we want to check.
