docs: Read or generate the xsrf token in its raw form.
  
          The raw_xsrf_token is a tuple containing:
  
          * version: the version of the cookie from which this token was read,
            or None if we generated a new token in this request.
          * token: the raw token data; random (non-ascii) bytes.
          * timestamp: the time this token was generated (will not be accurate
            for version 1 cookies)
