Setoptconf-tmp

Setoptconf-tmp is a temporary fork of the `setoptconf` library, designed to retrieve program settings from various sources like the command line, environment variables, INI files, JSON files, YAML files, and Python objects/modules. This fork was created to resolve compatibility issues with `setuptools >= 58` that affected the original `setoptconf` library, particularly for tools like `prospector`. The library is explicitly stated as a temporary solution, not actively maintained, and is expected to be purged once `prospector` updates or the original `setoptconf` is fixed. The current version is 0.3.1, last released in September 2021.
