feat(build): Add initial Nix-based build process
Adds a build script using ASDF's program-op to build an executable out
of the Gemma source code.

In addition a Nix derivation is provided that will both compile the
Elm source and place it in a folder, as well as create the executable.

Currently static file serving does not function as intended.
