M1 and M2 support on mac

[Simonlee711]

I think many packages in the meds ecosystem can benefit from a different set of instructions for M1 and M2 chips. I've had a difficult time working around getting polars to work properly. I recently installed python that does not run under Roseeta x86-64 but it still appears to come up short:

Resharding data
/Users/simonlee/opt/anaconda3/envs/py312/lib/python3.12/site-packages/polars/_cpu_check.py:259: RuntimeWarning: Missing required CPU features.

The following required CPU features were not detected:
    avx, avx2, fma, bmi1, bmi2, lzcnt, movbe
Continuing to use this version of Polars on this processor will likely result in a crash.
Install the `polars-lts-cpu` package instead of `polars` to run Polars with better compatibility.

Hint: If you are on an Apple ARM machine (e.g. M1) this is likely due to running Python under Rosetta.
It is recommended to install a native version of Python that does not run under Rosetta x86-64 emulation.

If you believe this warning to be a false positive, you can set the `POLARS_SKIP_CPU_CHECK` environment variable to bypass this check.
