DeprecationWarning for distutils package

[woidda]

It seems that distutils will be soon be obsolete.

/usr/local/lib/python3.10/site-packages/dataclass_csv/dataclass_reader.py:5
  /usr/local/lib/python3.10/site-packages/dataclass_csv/dataclass_reader.py:5: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
    from distutils.util import strtobool

Hi Walter!

Oh, good catch! Thank you so much for letting me know. 👍🏼

I will fix that. 👷🏼

Python 3.12 has been out for a few months, I tried to use the dataclass-csv package and I'm getting this error:

...lib/python3.12/site-packages/dataclass_csv/dataclass_reader.py", line 5, in <module>
    from distutils.util import strtobool
ModuleNotFoundError: No module named 'distutils'

The dataclass I am using for this doesn't even have any bool attributes, just some Optional[str] and mostly just str.

For what it's worth, adding a dependency on setuptools in my package works around the problem (since setuptools implements most or all of distutils, and patches sys.modules so that distutils references go to setuptools.

Also to confirm here that distutils is removed from Python 3.12, which is also mentioned in What's New In Python 3.12. Manually installing setuptools indeed fixes this issue. However, as I can see that distutil's only use is to convert string to bool, I guess implementing strtobool() manually wouldn't hurt.
