Packaging SlimeVR-Server

[Tobias Alexandra Platen]

I had a look at the SlimeVR Server which is written in Java and uses
the gradle build system. It also comes with a gui written in Javascript
and a Nix Flake:

I guess that I have to make two packages: slimevr-server (for the
server written in Java) and slimevr-gui (for the javascript part)
