Upload wheels to PyPI

Wheels (`.whl`) for this package are [currently missing from PyPI](https://pypi.org/project/pefile/2021.9.3/#files). Could wheels be uploaded for the current and future releases?

Read more about the [advantages of wheels](https://pythonwheels.com/) to understand why generating wheel distributions are important.

To create a wheel along with source distribution:

```bash
(venv) $ pip install --upgrade pip setuptools wheel build
(venv) $ python -m build

# See dist/*.whl
```

To upload wheels:

```bash
(venv) $ pip install twine
(venv) $ twine upload dist/*
````

Start by reviewing the package's current release process and run the provided `python -m build` command to inspect `dist/*.whl`. Use the documented `twine upload dist/*` flow to publish a wheel for the current release, then verify that it appears on PyPI and determine how future releases will include wheels.
