Improve platform support

[davnn]

Hi!

thanks for the great package. It would be great if we could provide pre-built packages for multiple platforms and Python versions and this pull request does exactly that.

Thanks,
David

Thank you, much appreciated.
However, the action does not appear to work entriely yet:

pypa/gh-action-pypi-publish@master
Error: Container action is only supported on Linux

It seems there is an additional step necessary, where the compiled artifacts are collected and (if all compiles were successful) uploaded: pypa/gh-action-pypi-publish#48 (comment)

[davnn]

Sorry, I didn't see that you already worked on it. Are there any problems still?

[kno10]

It seems to work, but I need to check whether it is worth to add cross-compilation for Linux targets on other CPUs, in particular aarch64, arm. Maybe musl, and of course for Apples new M1 CPUs.

I believe further support will only be possible hosting your own runners, see [1, 2], or using a different CI service. Not sure if that's worth the effort.

At least for linux, cross-compilation should be possible, e.g.,
https://github.com/messense/crfs-rs/blob/0e77658d65abefef8818cc25b0a57941ff41269b/.github/workflows/Python.yml#L105-L109
and there appears to be a github action docker image for osxcross, too (but it does not mention aarch64-apple-darwin for M1):
https://github.com/marketplace/actions/shogan-rust-static-build
but M1 does not appear to be perfectly supported yet by rust tooling: rust-lang/rust#73908
