Add py-whitenoise 4.1.2

Radically simplified static file serving for Python web apps

With a couple of lines of config WhiteNoise allows your web app to serve its own
static files, making it a self-contained unit that can be deployed anywhere
without relying on nginx, Amazon S3 or any other external service. (Especially
useful on Heroku, OpenShift and other PaaS providers.)

It's designed to work nicely with a CDN for high-traffic sites so you don't have
to sacrifice performance to benefit from simplicity.

WhiteNoise works with any WSGI-compatible app but has some special auto-
configuration features for Django.
