eate a mask from the two sequences passed to be used in a sequence-pair classification task. RoBERTa does not:
        make use of token type ids, therefore a list of zeros is returned.
            token_ids_0 (`List[int]`):
                List of IDs.
            token_ids_1 (`List[int]`, *optional*):
                Optional second list of IDs for sequence pairs.
        Returns:
            `List[int]`: List of zeros.
