    A generic op for any TFLite custom operation.

    input: A list of inputs in the original op.
    custom_code: A string used to identify which exactly this op is, which
                 corresponds to operator_codes.custom_code in the flatbuffer.
    custom_option: a holder to save the op attributes in bytes fashion.
    output: A list of outputs in the original op.
