OpCodeGenerator is unimplemented for Softplus

[juhan]

When trying to convert a Yolov4 ONNX model with onnx-pytorch I get the following error. Seems to be an unimplemented OpCode for Softplus.

WARNING:root:Cannot get default value for dilations of Conv. WARNING:root:Cannot get default value for kernel_shape of Conv. WARNING:root:Cannot get default value for pads of Conv. WARNING:root:Cannot get default value for strides of Conv.
