Nice! LGTM. Will probably merge and do an alpha release tomorrow. Thanks again @alugowski! |

Builds Linux aarch64 wheels using cibuildwheel's built in multi-arch support: https://cibuildwheel.readthedocs.io/en/stable/faq/#emulation
Inspired by matplotlib's approach: https://github.com/matplotlib/matplotlib/blob/main/.github/workflows/cibuildwheel.yml
This uses QEMU emulation since GitHub only offers x86 Linux runners. Cross-compilation isn't built into cibuildwheel yet.
Emulation is about 5x slower than native, but is all-inclusive including the libgraphblas build.
More types are disabled (only for aarch64) because otherwise
suitesparse.shonly achieves about 70% complete in the 6-hour time limit.cibuildwheel can use the same Linux runner for all Linux architectures. This PR uses a separate runner for aarch64 only. This way aarch64 has the full 6 hours, and also any general wheel issues still show up quickly in the x86 build. The aarch64 build runtime is about 5:15.
NOTE: this is based on the macOS ARM branch #83 NOT main! Merging this will merge that as well. The reason is a change in specifying CIBW_ARCH that would cause a merge conflict.
