Re-do the twine upload because the classifiers are not showing on pypi

[simkimsia]

when the version was 2.0.0, the classifiers did not show up

In the alpha version before 2.0.0

In the 2.0.0

Probably need to recreate the package and upload it since the setup.cfg looks correct.

# Create the package
python setup.py sdist bdist_wheel

# Upload it to PyPI
twine upload dist/*
