Build Python3 wheels

[brunobord]

This needs to be scripted:

• get only releases that are/were compatible with Python3
• eventually check that we can build them using Python 3.6, even if they weren't Py3.6 compatible.
• don't forget to remove the build/ repository before rebuilding (following @ewjoachim's advice)
• push to PyPI

(if you're building wheels for py3 only, then you won't need the "universal = True" that everyone puts everywhere)

here's the script I've used (yes, it could've been bash, but I never remember how to make a loop):

from shell import shell
from distutils.version import StrictVersion

result = shell('git tag')
tags = result.output()
tags = filter(lambda x: not x.startswith('v'), tags)  # That was a mistake
tags = filter(lambda x: StrictVersion(x) >= StrictVersion("1.0.0"), tags)

for tag in tags:
    print(tag)
    shell(f'git checkout {tag}')
    shell('rm -Rf build/')
    result = shell('python setup.py bdist_wheel')
    if result.code:
        print(result.errors())

shell('git checkout master')

currently uploading every wheel from 1.0.0 to the latest release without any Py3 wheel.
