install fails if setuptools >= 58

[myourshaw]

pip3 install PyVCF (version 0.6.8) will fail when setuptools version is >=58. Instead PyVCF will install version 0.4.3, which fails to run with this error:
ImportError: cannot import name 'Reader' from 'parser' (/home/myourshaw/.local/lib/python3.9/lib-dynload/parser.cpython-39-x86_64-linux-gnu.so)

Python version is 3.9.7
`
pip3 install --upgrade PyVCF;

In looking at some of the code, I sense it is Python2 still:

File "/home/mothcw/Downloads/PyVCF-master/vcf/parser.py", line 644, in Writer
counts = dict((v,k) for k,v in field_counts.iteritems())
AttributeError: 'dict' object has no attribute 'iteritems'

I hope the maintainers might move the entire thing to Python3 and call it Version 0.7.0
