docs: Transmit arbitrary data and receive the response.
  
          This is a low level method to send arbitrary data to the
          tag. While it should almost always be better to use
          :meth:`send_apdu` this is the only way to force a specific
          timeout value (which is otherwise derived from the Tag's
          answer to select). The *timeout* value is expected as a float
          specifying the seconds to wait.
