Add nteract support for JupyterPlot

For nteract, any Jupyter kernel that returns Plotly's JSON Chart Schema with mimetype application/vnd.plotly.v1+json can go straight from a dict/object/map to render:

Thanks for opening this @jackparmer.

Sorry for the delay in responding

I would love to get nteract support for this package.

@rgbkrk thanks for the example. It seems like it should be pretty straightforward. If I have any issues do you mind if I ping you for pointers?
