Installing fails on Python 3.12; versioneer update needed?

[gerritholl]

Trying to install pytroll-collectors fails on Python 3.12. The failure apparently happens due to an outdated version of versioneer, which refers to SafeConfigParser, a class that has been removed.

In a clean repo, pip install pytroll-collectors fails with:
