    Retrieves sequence ids from a token list that has no special tokens added. This method is called when adding
    special tokens using the tokenizer `prepare_for_model` or `encode_plus` methods.
    Args:
        token_ids_0 (`List[int]`):
            List of ids of the first sequence.
        token_ids_1 (`List[int]`, *optional*):
            List of ids of the second sequence.
        already_has_special_tokens (`bool`, *optional*, defaults to `False`):
            Whether or not the token list is already formatted with special tokens for the model.
    Returns:
        A list of integers in the range [0, 1]: 1 for a special token, 0 for a sequence token.
