Pre-install additional packages with emscripten-forge

Using the xeus-r kernel, you can pre-install packages from either conda-forge or emscripten-forge by specifying them in the environment.yml file in the JupyterLite build directory.

By pre-installing packages, they are readily usable in the kernel and can be imported without the need of installing them in the notebook.

As an example, a deployment can easily be made using the Xeus-Lite demo.

This demo follows the same steps as the quickstart guide but uses Xeus R as the kernel.

Check out the jupyterlite-xeus documentation for more information.
