OMpy installation issue on Mac with the M1-chip

[andreashmj]

I have successfully managed to install OMpy on my MacBook with the M1-chip. However, I had problems with some of the compilation flags in setup.py. The consequence was that the command

pip install -e .

failed.

Fix:
The workaround for me has been to remove the flags "march=native" and "mfpmath=sse" in setup.py, which seem to be invalid for Apple M1. Then the pip installation works fine.

Hi,

I've made a PR with a fix. In theory the march=native flag shouldn't break any compilation as it tells the compiler only to optimise for the specific CPU of the system. The mfpmath=sse flag is x86 specific. I've changed the setup to ensure that this is disabled for non-x86 platforms.

@andreashmj could you try to install with this: https://github.com/vetlewi/ompy/archive/refs/heads/fix/issue/190/M1-compile-issue.zip?
