Python 3.12 incompatible with versioneer

[thelostscout]

When installing bgflow with pip in a conda env based on python 3.12, I find the following error:

File "<string>", line 2, in <module>
File "<pip-setuptools-caller>", line 34, in <module>
File "/tmp/pip-install-zhnn22g8/bgflow_eb74916574b843488e1884c71c62d8f8/setup.py", line 30, in <module>

  parser = configparser.SafeConfigParser()
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'configparser' has no attribute 'SafeConfigParser'. Did you mean: 'RawConfigParser'?

According to this comment: pydata/pandas-datareader#969 (comment), versioneer isn't compatible with modern python anymore.
