Package vulnix as nix flake

[henrirosten]

Package vulnix as nix flake:

• initialize vulnix nix flake
• introduces flake.parts for a modular approach to composing the flake outputs
• adds flake-compat to ensure non-flake users can work with the repo
• configures nix devshell with vulnix required python dependencies
• configures treefmt for nix fmt which enables the following:
  • black to format .py files
  • isort to sort imports in .py files
  • nixfmt to format .nix files
  • deadnix to remove dead nix code
  • statix to avoid nix anti-patterns
  • mixes in a flake check
• applies the initial formatting changes
