        Fire an event on the master bus

        If `fire_event` is set to True an event will be sent with the
        chunk name in the tag and the chunk result in the event data.

        If `fire_event` is set to a string such as `mystate/is/finished`,
        an event will be sent with the string added to the tag and the chunk
        result in the event data.

        If the `state_events` is set to True in the config, then after the
        chunk is evaluated an event will be set up to the master with the
        results.
