Get the .ipynb notebook file path from a running Jupyter notebook

The way this works is that for each notebook, jupyter starts a python "kernel" process that actually runs the notebook's code. That kernel gets a json file with info on the notebook's location on the disk passed through its command line. Since we're running code in that exact python process, we can just grab that json file from sys.argv, and read it ourselves.
