Adds pygame recipe

Robert Pfeiffer · AndreMiras · commit b20fbaf5bb77 · 2020-05-01T10:19:11.000+02:00
As discussed on the Discord, this is a recipe to build apps based on SDL2-based pygame. It currently references https://github.com/pygame/pygame/tree/android, a branch that will continue to live until we have an official stable release of pygame based on SDL2 with android support. Simple examples have been tested by other pygame users (it doesn't just build on my own machine) but some pygame functionality is still untested, and some dependencies like freetype, postmidi and libjpeg are currently not part of the build. It's usable, but not complete.
