Jupyterlab 2.0 support

@nicolaskruchten I actually just did a fresh install of everything (jupyter lab, plotly, pandas etc) on my box and am getting the following errors:

and the log says the same thing

ValueError: The extension "@jupyterlab/plotly-extension" does not yet support the current version of JupyterLab.


Conflicting Dependencies:
JupyterLab                        Extension      Package
>=2.0.1 <2.1.0                    >=1.3.0 <2.0.0 @jupyterlab/rendermime-interfaces

Exiting application: jupyter

I used the following command to install the extension:

jupyter labextension install @jupyterlab/plotly-extension
