Ensure package supports installation of dev environment via pip

[laurejt]

It should be possible to install the development python environment using pip rather than uv.

pip install -e ".[dev]" should complete without error.

Currently, encountering the following error for a python 3.12 environment (conda/mamba):

ModuleNotFoundError: No module named 'pkg_resources'
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed to build 'pandas' when getting requirements to build wheel
