🐛 Installation fails, cannot build matplotlib.

[astrogewgaw]

Lately the installation for candies fails, since it cannot seem to build matplotlib. This happens since proplot, which is a thin wrapper around matplotlib, only supports matplotlib v3.4 and below, at least as far as it latest release on PyPI is concerned. matplotlib depends on versionner for its semantic versioning, which currently fails for matplotlib v3.4, but surprisingly does not fail for matplotlib v3.5 and above. From what I could trace, this is due to the removal of SafeConfigParser from the configparser module in the standard library in Python 3.12 (see python/cpython#89336). At least that is how deep the rabbit hole seems to go. Someday, when Python stops shipping breaking changes between minor versions, stuff like this won't be a problem.

Note: This will be fixed when #3 is merged. We are now depending directly on the main branch of proplot, which supports matplotlib v3.5. Hopefully this does not result in too many breakages in candies 🤞🏾.
