[renamerOnUpdate] [feature] user-defined paths that will be completely ignored

To create a variable, $ignore_dir, that lets a user define multiple directory paths that renamerOnUpdate will completely ignore.

$ignore_dir = {}

Example usage:

$ignore_dir = {
   "/mnt/stash/library/downloads",
   "/mnt/stash/library/unorganized"
}

Discord user Clairambie has already provided functioning code. However his version only accepts a single folder in the $ignore_dir variable.
