Add Jupyter Notebook example for signing and verifying a model

[font]

Closes #169

Summary

Help make it easier to incorporate signing and verifying models into notebooks. To test, install Jupyter Notebook and run it locally inside the model_signing directory containing the notebook:

cd ./model-transparency/model_signing
jupyter notebook

Then open the sign_and_verify_model.ipynb notebook and execute it. Note that certain steps are interactive and the execution will halt at various cells waiting for input from the user.

Thank you for the PR and the issue.

I'll take a closer look, but overall, this looks like it extracts parts of the CLI code into notebook cells and makes the notebook be the driver for signing. Please correct me if I was wrong, I only skimmed through this right now.

We are working on making a library for signing so people don't need to copy code, just call an API.

Yes, that's correct!

Where is this work happening? Happy to help in any way I can.
