Setup a development environment

Once PDM and Nox are installed, it is very easy to setup a development environment for PyLandStats. On most systems, one can install PDM and Nox with Pipx, with something like:

python3 -m pip install pipx
python3 -m pipx ensurepath

and then in a new terminal:

pipx install pdm
pipx install nox

Once PDM is installed, clone the PyLandStats repo and run make from the root directory. This should install a dedicated local virtual environment .venv. You can then activate it and run the tests.

Note that there are few other targets in the Makefile useful for developers. In particular, it is good to periodically recompute the dependencies written in the pdm.lock file (with make lock) to check if new packages uploaded on PyPI do not break PyLandStats. It is reasonable to do this in a dedicated PR.
