Manylinux ARM builds

[fidoriel]

Hey, it would be great if you could supply manylinux arm builds for pyrage. For example for M1 Docker builds or Raspberry Pi.

Thanks for the request. I can look into this in the upcoming days. Alternatively, if you feel like it, I'd be happy to review a PR that updates the current CI/build matrix to add ARM wheels.

I took a quick look at this, and it looks like this won't be super straightforward: GitHub's arm64 Linux runners are in GA, but they're only available to paying orgs/enterprises.

The alternative is to cross-compile or use something like QEMU. For the former, maturin-action looks to be the most promising approach.

Used qemu in other projects with the official action, that did the matrix stuff on qemu. Sadly do not have the time to contribute currently.

I gave this a shot now that arm64 hosted runners are available for free in public repositories, but it didn't go so well. The release builds went OK, but the tests failed during build: https://github.com/magnuswatn/pyrage/actions/runs/12867324778/job/35871841340. Haven't looked into the error.

That looks like a segfault in typenum's build: https://github.com/paholg/typenum/tree/main/build

Not sure why it would segfault, however -- I see no use of unsafe in the build.

Edit: It seems to actually be rustc's failure on that crate, so perhaps a compiler bug.
