Publish wheels for macOS ARM

[BoboTiG]

Waiting on pypa/cibuildwheel#484 before giving a try.
That will ease the support of new Apple Silicon machines.

Oh, that would be great :) I'm not sure about the state of Python packaging but a universal wheel might also be good.

Watchdog is currently my only Python dependency with an extension module and therefore keeping me from shipping a fully universal app bundle.

@samschott Python packaging can definitely handle a universal wheel 😅 This project, however, can't ship a universal wheel because it requires platform-specific built distributions for macOS.

@BoboTiG Looks like this was added in https://pypi.org/project/cibuildwheel/1.9.0/. The pipeline here just uses the latest version, so the next release should include the ability to build for Apple Silicon via cross-compiling: https://cibuildwheel.readthedocs.io/en/stable/faq/#apple-silicon

@di, apologies, I should have been more precise. I meant "univeral2" wheels as in macOS universal binaries (combined binaries for Apple Silicon and Intel Macs). Looking at the docs, this does seem to be supported by cibuildwheel.

I'm including watchdog as a dependency in a macOS app bundle and having a universal .so file served from PyPI would simplify the packaging process.

Ah, got it! Yes it shouldn't be a problem to publish a universal2 wheel here in addition to the architecture-specific ones.

macOS arm64 and universal2 wheels are online :)

Nice! Greatly appreciated :)
