Changelog:
==========
- Allow pypng factory to allow for saving to a string
(like qr.save("some_file.png")) in addition to file-like objects.
- Fix bad over-optimization in v7.4 that broke large QR codes. Thanks to
mattiasj-axis!
- Restructure the factory drawers, allowing different shapes in SVG image
factories as well.
- Add a --factory-drawer option to the qr console script.
- Optimize the output for the SVGPathImage factory (more than 30% reduction in
file sizes).
- Add a pypng image factory as a pure Python PNG solution. If pillow is not
installed, then this becomes the default factory.
- The pymaging image factory has been removed, but its factory shortcut and the
actual PymagingImage factory class now just link to the PyPNGImage factory.
