Add a reshape layer. Kindly refer to NeuralNetwork.proto for details.

        Parameters
        ----------
        name: str
            The name of this layer.
        target_shape: tuple
            Shape of the output blob. The product of target_shape must be equal
            to the shape of the input blob.
            Can be either length 3 (C,H,W) or length 4 (Seq,C,H,W).
        mode: int

            - If mode == 0, the reshape layer is in CHANNEL_FIRST mode.
            - If mode == 1, the reshape layer is in CHANNEL_LAST mode.

        input_name: str
            The input blob name of this layer.
        output_name: str
            The output blob name of this layer.
