docs: Clears any cached info that was exported from the OS trust store. This will
      ensure the latest changes are returned from calls to get_list() and
      get_path(), but at the expense of re-exporting and parsing all certificates.
  
      :param temp_dir:
          The temporary directory to cache the CA certs in on OS X and Windows.
          Needs to have secure permissions so other users can not modify the
          contents. Must be the same value passed to get_path().
