Rust Jupyter Kernel

%%bash

# https://github.com/google/evcxr/blob/main/evcxr_jupyter/README.md
cargo install evcxr_jupyter
evcxr_jupyter --install

# make sure the kernel finds the rust tools ... (since the path is not setup when Jupyter starts)
sudo ln -s ~/.cargo/bin/cargo /usr/local/bin/cargo

Now the kernel is available from the Launcher. A restart of the micropython service may be needed.
