After quantification, add pipeline operation

[119458]

❓Question

After I trained the yolov8 model, I used coremltools==7.0 to convert it into an mlpackage model. Then, I quantified the model using the pruning in the official documentation. After quantification, I added nms operations to the model using the pipeline mechanism. I imported the model with nms added into xcode and input the predicted images. xcode crashed directly. By importing an nms model without adding quantization operations, xcode could predict the results normally
