Nix build & development

[danmur97]

Hi, I want to setup a development environment for win2xcur via nix. Commonly it should be using nix develop over the win2xcur nix package, however I would like to enable it using direnv instead, making it shell-independent.

Also I would like to spread the use of nix, by integrating the nix build process on the original source repo of the package, rather than been separated on the nixpkgs repo.
