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.
Args:
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.
