        Merge any thing information in a signal event together with extra fields from signal enrichment. Thing events contain thing information. All other signals do not contain thing information. Extra fields contain thing information if it is not empty. If thing information exists in any of the 2 sources, then merge the information from both sources to create a thing, with priority given to the thing information extracted by the signal.
        Parameters:
        signal - the signal.
        extraFields - selected extra fields to enrich the signal with.
        extra - value of the extra fields.
        Returns:
        the merged thing if thing information exists in any of the 2 sources, or an empty optional otherwise.
