Deprecation warning when adding pyvipr to version 4 of JupyterLab

[blakeaw]

Hi,

This is just a heads up for the following jupyter labextension install deprecation warning I got when adding pyvipr to JupyterLab 4.0.1:

(Deprecated) Installing extensions with the jupyter labextension install command is now deprecated and will be removed in a future major version of JupyterLab.

Users should manage prebuilt extensions with package managers like pip and conda, and extension authors are encouraged to distribute their extensions as prebuilt packages

I got the warning for both commands:

jupyter labextension install @jupyter-widgets/jupyterlab-manager and jupyter labextension install pyvipr
