Scan results quality for Python packages: wheel vs. source distributions

[tdruez]

While the "License clarity" and "Scan summary" data looks great when using source distributions, the quality of the results when using wheel as inputs could be improved.

• Wheel: XlsxWriter-3.0.3-py3-none-any.whl

When looking at the LICENSE.txt and METADATA key files of the wheel, it seems that we should be able to get the Declared license and Declared holder value as we do for the source dist:
