Incorrect license info in setup.py

[anntzer]

setup.py currently contains the lines

classifiers = [
    <...>
    'License :: OSI Approved :: Python Software Foundation License',
    <...>
    ]

and

        license="BSD",

which are in contradiction with one another. (Considering the actual contents of the LICENSE file, I think the second instance should be changed to license="PSF".)
See also https://packaging.python.org/specifications/core-metadata/#license for the metadata spec.

They are all at least in the same family (see for JDH's motivations https://matplotlib.org/devel/license.html#license-discussion) .....

I don't actually personally care much, but thought you might.

Yeah, I have been reading licensing things for the last 30 minutes....
