Python environment does not change to match when overriding ESP-IDF version

[mirrexagon]

#24 points out that since #23 changed from using mach-nix to dynamically read the requirements file to manually packaging and including the necessary Python packages, overriding the ESP-IDF version (see examples/shell-override-versions.nix) doesn't adapt the Python environment, making overriding the version less useful.

I would like an automated way to check `requirements.core.txt, the latest constraints file (eg. https://dl.espressif.com/dl/esp-idf/espidf.constraints.v5.1.txt), and the latest versions of those packages on PyPi against the Python packages I have packaged here, to make it easy to see what is missing or could be updated.

Note to self, could https://github.com/nix-community/nix-init help us?

I'm running into this issue when trying to compile a project depending on ESP IDF 5.0.1: the Python dependencies are declared incorrectly. Is there any advice on compatibility with a toolchain this old? Going through the commit history, it seems at one point a parsing on the requirements.txt was done, but has since been converted into a static list of dependencies?

Yeah, I re-did the Python packages because we were using mach-nix before and it isn't supported anymore and started breaking anyway. I'm not sure what another good solution is right now to adapting the Python environment to the overridden version.
