Testing Leptos as a static site generator (SSG)

The continuation of this is the static site generator Cinnog

This project uses a custom branch of Leptos to be able to directly serve the output directory as a static website.

cargo make serve serves the div directory with watch mode and hot-reload enabled. cargo make build builds the project in release. The output will be in the dist directory and the command will not serve it, but quit instead. cargo make fmt formats with rustfmt and leptosfmt.
