Expose maintainers

[stefan6419846]

Some packages do not have the author field set, but the maintainer one (example: https://github.com/opencv/opencv-python/blob/b776e5ce9f164600a1bd05178a058272122bf02a/setup.py#L272). Exposing the maintainer as well would allow users to work with the maintainer value if the author value would be empty otherwise.

Good suggestion.

For example, would you prefer OpenCV Team(maintainer) as the output result, or simply OpenCV Team ?

[stefan6419846]

This depends on the output format in my opinion. For me, a new key maintainer returned by piplicenses.get_packages would be sufficient as I am rendering the results myself and can decide on how I want to display maintainers. I am not sure about the actual rendered output though, as I am not actually using it.

Then, it might be a good idea to output a new column like --with-maintainers.

Think of something and prepare a release candidate version.

@stefan6419846 A release is planned to resolve this suggestion.

The next release candidate version has been uploaded to PyPI.
https://pypi.org/project/pip-licenses/4.2.0rc1/

Install it in your environment and make sure it is working as expected.

pip install pip-licenses==4.2.0rc1

There is some time before the official release. Feedback is welcome.

I just did a quick test and could everything seems to work as expected. Thanks.
