The macos-13 runner is being deprecated.

This means we may have to remove a build of musica on mac for x86_64 based systems, or potentially cross-compile

Acceptance criteria

• no github actions reference macos-13
• Replace macos-13 with an x86_64 compatible image, which might be macos-14-large, or maybe macos-latest-large, macos-15-large, or macos-15-intel
• python x86_64 wheel for mac is created, if possible

Ideas

• Look at other images here if needed
