Python fat binary so bsdiff4 >= 1.2.4?

[walt-jones]

We're trying to compile a universal2 executable and have been unable to find/install a fat binary for bsdiff4 >= 1.2.4. arch -x86_64 -arm64 pip3 install bsdiff4 still gives us separate architectures so files and Pyinstaller builds fail with a IncompatibleBinaryArchError error on /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/bsdiff4/core.cpython-312-darwin.so. Any way to get a fat binary of bsdiff4 for MacOS?

We were able to use lipo to combine x86_64 and arm64 architectures into a single .so and this satisfied Pyinstaller's requirements for fat binary. No further action required. Thanks!
