    Constructs a BridgeTower processor which wraps a Roberta tokenizer and BridgeTower image processor into a single
    processor.

    [`BridgeTowerProcessor`] offers all the functionalities of [`BridgeTowerImageProcessor`] and
    [`RobertaTokenizerFast`]. See the docstring of [`~BridgeTowerProcessor.__call__`] and
    [`~BridgeTowerProcessor.decode`] for more information.

        image_processor (`BridgeTowerImageProcessor`):
            An instance of [`BridgeTowerImageProcessor`]. The image processor is a required input.
        tokenizer (`RobertaTokenizerFast`):
            An instance of ['RobertaTokenizerFast`]. The tokenizer is a required input.
