Loads pnpm’s shrinkwrap.yaml into nix expressions.

Example default.nix

with (import /path/to/pnpm2nix { inherit pkgs; });

mkPnpmPackage {
  src = ./.;
  # These default to src/package.json & src/shrinkwrap.yaml
  # packageJSON = ./package.json;
  # shrinkwrapYML = ./shrinkwrap.yaml;
}

More comprehensive examples can be found in the tests.
