Hardcoded `UInt8` idtype in FakeQuantWithMinMaxArgs causes error

1

These two lines look odd to me... Why hard code the input dtype to uint8? https://github.com/onnx/tensorflow-onnx/blob/482330f9958eb45c805933f04e2b0a5c7a494f23/tf2onnx/onnx_opset/quantize.py#L57 https://github.com/onnx/tensorflow-onnx/blob/482330f9958eb45c805933f04e2b0a5c7a494f23/tf2onnx/onnx_opset/quantize.py#L63-L68 I got the following error when converting QAT-ed yolo4 model from https://github.com/openvinotoolkit/nncf/tree/develop/examples/tensorflow/object_detection.
