A few files have not been changed in this PR because they would cause rebuilds.

This PR should have 0 rebuilds.

This commit was created by a combination of scripts and tools:
- an ast-grep script to prefix things in meta with `lib.`,
- a modified nixf-diagnose / nixf combination to remove unused `with
lib;`, and
- regular nixfmt.

Upstream has switched from flit to hatch.

Remove six and enum34 dependencies that are no longer needed because
argon2-cffi doesn't support Python 2.

Also, remove the wheel test dependency, which doesn't appear to be
required anymore.

argon2-cffi-bindings uses a vendored copy of libargon2 by default, but can
be configured to use a system installation. This reduces the output size
avoids issues with the build system mistakenly trying to use SSE2 on
non-x86 platforms when cross-compiling.

argon2-cffi-bindings needs cffi at build time and run time, therefore it has
cffi in nativeBuildInputs and propagatedBuildInputs. argon2-cffi doesn't
directly use cffi, only transitively through argon2-cffi-bindings. This also
removes a problematic usage of propagatedNativeBuildInputs.

Also, add pythonImportsCheck to verify that we have all the necessary
dependencies.
