activatedgeek/LeNet-5 use ONNX for inference

Now let's try and use the trained ONNX file for inference on some manually drawn images on GIMP:

Note that the images must be drawn with white on black. If you use black on white, it the accuracy becomes terrible. This is a good very example of brittleness in AI systems!

We can try the code adapted from thenewstack.io/tutorial-using-a-pre-trained-onnx-model-for-inferencing/ at python/onnx_cheat/infer_mnist.py: and it works pretty well! The protram outputs: as desired.

We can also try with images directly from Extract MNIST images. and the accuracy is great as expected.
