aarch64 and osx-arm64 wheels

[IAlibay]

To match the existing MDAnalysis deployment, pypi and conda-forge wheels for aarch64 and osx-arm64 should be made available.

conda-forge needs MDAEncore added to the migration list; that's a simple enough process

pypi wheels will need creation via Cirrus and CIBuildWheels. We can copy most of the pipeline from MDAnalysis here, but we'll need to make sure we don't exceed the number of credits we have available to us.

Build deployment: conda-forge/mdaencore-feedstock#5

@MDAnalysis/encore maintainers, input would be appreciated here.

1. Reviews on conda-forge are needed
2. A decision on pypi wheel creation and who can carry out the work would be great.

Thanks a lot for doing this! I submitted the review. It's great if we can use the CI setup from MDAnalysis but I have no experience with Cirrus or CIBuildWheels so I don't have much input on this.

Thanks for the reviews @enoee !

With #63 merged in there are now arm64-osx wheels on pypi and conda-forge.

If I get some spare cycles I might try to remember how we did ppc64le and aarch64 on the core library for conda-forge.
For PyPi, my recommendation would be to not bother with aarch64 - the number of folks that need linux arm64 wheels is really small, especially for encore where you tend to need a lot of RAM.
