Subject: [PATCH] build(flake): ensure that nix flake have deterministic
 outputs

TODO:
Install dependencies declared in `pyproject.toml` through nix
instead of pip so as to pin the python dev dependencies. The old way
to do this is pinning them in `requirements-dev.txt` generated by
pip-compile and reproducing with pip-sync in a virtual environment.

After doing this, build this lib as a nix python package.
