libopenblas version > 0.3.23 causes OpenMP error on Mac

🐛 Bug

Building wheels with libopenblas version > 0.3.23 causes the following OpenMP error on Macs (both x86_64 and arm64):

OMP: Error #15: Initializing libomp.dylib, but found libomp.dylib already initialized.
OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results. For more information, please see http://openmp.llvm.org/
Abort trap: 6

This seems to be due to the wheel delocation; libopenblas 0.3.24 and larger specifically seem to be the issue, as this issue does not occur with earlier libopenblas.

Issue fixed for now by pinning libopenblas to 0.3.23 in #652.

Reproducible example

import galpy; print(galpy.__version__)
from galpy.potential import MWPotential2014
from galpy.orbit import Orbit

Expected behavior

Should just work.
