py-qrcode: updated to 7.4.2

7.4.2 (6 February 2023)

- 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!

7.4 (1 February 2023)

- Restructure the factory drawers, allowing different shapes in SVG image
  factories as well.

- 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 actual PymagingImage factory class now just link to the PyPNGImage
  factory.
