MVP get us working fully on nixos
NB: for now this is linking to a presumed local clone of the `poetry2nix` repo since part of fixing what was adjusted here needs to be patched upstream, which means hackin on the p2n repo in tandem B) Since there's some dependency build issues we need to tweak the following to get baseline `nix develop` working: - drop `python-levenshtein` (required by `fuzzywuzzy[speedup]`) for now since the overlay and/or wheel install needs to be properly figured out. - build `pyqt5` from src for the moment (since `preferWheel` doesn't seem to be workin?) despite it taking forever XD - add in the `flake.lock` file.poetry2nix

# NOTE: to convert to a poetry2nix env like this here are the
|

# steps:
|
||||
# - install poetry in your system nix config
|
||||
# - convert the repo to use poetry using `poetry init`:
|
||||
# https://python-poetry.org/docs/basic-usage/#initialising-a-pre-existing-project
|
||||
# - then manually ensuring all deps are converted over:
|

# - add this file to the repo and commit it
