Submodules not included in archive tarball

Hi!

When downloading the juCi++ tarball from GitHub, submodules are not included. It would be nice to have an option to download a release tarball with all the necessary submodules (see https://github.com/DaveDavenport/rofi/releases for an example).

This is helpful when packaging for other distributions (Guix in my case).
