Compare dist sizes vs latest PyPI release

[hugovk]

This helps us keep a handle on additions such as #7848 which considerably increase the size of wheels.

It adds this extra job to the wheels run:

It compares the wheels just build against the last release on PyPI.

• Wheels which are on PyPI but no longer local (such as cp313-cp313t-macosx_10_13_x86_64.whl -- experimental 3.13t wheels have been dropped Drop experimental Python 3.13 free-threaded wheels #9535) are not counted in the total.

• Wheels that are both on PyPI and local are included in the total.

• New wheels in local are included in the total.

For example, here's the top and bottom of the long table:

Example:

• https://github.com/hugovk/Pillow/actions/runs/24994389047 > Compare dist sizes vs PyPI summary > Load summary
• https://github.com/hugovk/Pillow/actions/runs/24994389047/job/73199266007#step:5:12

The script can also be run against a local dir of wheels. For example:
