idea: Flake Module

[kolloch]

I started experimenting a little bit with building a flake module for nix2container.

I plan to expose most of the nix2container API one-to-one but also add some convenience more high-level stuff on top.

This is in an early stage but feel free to chime in:

I would just hope for an overlay to avoid arbitrary having more versions of nixpkgs laying around than necessary.

overlay seems worked good in many cases
