Add aarch64 linux wheel

[davnn]

As mentioned in #17, this pull request adds an arm64 build to the CI pipeline. Appears to work beautifully :)

Did not work for me on Github. Unfortunately, I only got an entirely useless error message; but this could be due to some temporary failure

 + /opt/python/cp310-cp310/bin/maturin build -i /opt/python/cp310-cp310/bin/python --release --strip
💥 maturin failed
  Caused by: Cargo metadata failed. Does your crate compile with `cargo build`?

Interesting, the same pipeline worked for me, see [1] and [2], but, as you said, it might be a temporary failure.

It may be an OOM issue with cargo update, judging from the exit code.
Maybe you have a higher memory limit than me for github actions in your pro account?

+ cargo build --release --verbose
    Updating crates.io index
.github/workflows/build-wheels.sh: line 10:   150 Killed                  cargo build --release --verbose
Error: Process completed with exit code 137.

Adding an unreasonably low "ulimit -v 6000" causes the same error code on native amd64. OTOH, there appear to be 6+GB available, and I can run cargo update here with 1 GB ulimit.

This appears to be cargo#10583, although that does not explain why it worked for you.

It seems to work now, but it takes 60 minutes with qemu to build, and somehow github actions were stuck for quite some time after cleanup of the container.
Anyway, aarch64 packages appear to be available now (no version number change) on https://pypi.org/project/kmedoids/#files

This maturin-action seems to already automate this for more platforms: https://github.com/messense/maturin-action
and maybe we can use this in the future.
