pip: do not know how to unpack source archive xxxx.whl

I tried packaging a pip module: https://codeberg.org/raboof/nix-vulnerablecode

... but it fails to unpack the .whl:

      > Using setuptoolsShellHook
       > Sourcing pypa-install-hook
       > Using pypaInstallPhase
       > Sourcing python-imports-check-hook.sh
       > Using pythonImportsCheckPhase
       > Sourcing python-namespaces-hook
       > Sourcing python-catch-conflicts-hook.sh
       > unpacking sources
       > unpacking source archive /nix/store/01nnkk77w2vi7jv9g3yjlmrphyc40wdk-vulnerablecode-33.6.3-py3-none-any.whl

Is it incorrect that this is pointing to a whl, or that it fails to unzip the whl, or is the way this software is packaged not supported by dream2nix?

This should be supported. For some reasons, your flake end's up with buildPythonPackage.format = "setuptools";, while it works with

  buildPythonPackage.format = "wheel";

This should be set as a default in

dream2nix/modules/dream2nix/pip/default.nix

Line 58 in 1c2b47f

if l.hasSuffix ".whl" cfg.mkDerivation.src

if mkDerivation.src ends with '.whl', which packages.x86_64-linux.default.config.mkDerivation.src does according to my nix repl.
