Update qrcode[pil] requirement from ~=6.1 to ~=7.4 in /aries-backchannels/mobile

[dependabot[bot]]

Updates the requirements on qrcode[pil] to permit the latest version.

Changelog

Sourced from qrcode[pil]'s changelog.

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.

7.4.1 (3 February 2023)

• 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.

• 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.

7.3.1 (1 October 2021)

• Improvements for embedded image.

7.3 (19 August 2021)

• Skip color mask if QR is black and white

7.2 (19 July 2021)

• Add Styled PIL image factory, allowing different color masks and shapes in QR codes
