Issue while installing with setuptools==46

Hi guys,

when I tried to install kaitaistruct for python I got this error message:

This disappeared when I downgraded my setuptool version from 46.0.0 to 40.0.0

Would #39 bring a solution to this problem?

This error is caused by setup.py files trying to read setup.cfg manually, which is not officially supported (see pypa/setuptools#1869). You're supposed to just call setup() without arguments and let setuptools find and read the setup.cfg file itself.

Yes, this would be fixed by #39, but I personally still think that the PR is not acceptable in its current state - see my review comments on the PR, specifically the ones about Python 2 compatibility.

Fails on setuptools==44.0.0 also.

... and I can't downgrade to setuptools <44.0.0 because there's none in Gentoo.
Also can't downgrade Kaitai runtime version to 0.8.0 as I have to use devel IDE cause of kaitai-io/kaitai_struct_webide#68 . Sweet.

Tried #39, works for me. But I don't care about Py2.
