QuTip fails on import with numpy 1.22.1

See original GitHub issue

Qutip works fine with numpy 1.21.1, but fails on import with 1.22 numpy, released Dec 31st. Tested on ubuntu and MacOS.

>>> import qutip
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/work/miniconda3/envs/QF9/lib/python3.9/site-packages/qutip/__init__.py", line 73, in <module>
    (_blas_info() == "OPENBLAS" and platform.system() == 'Darwin')
  File "/Users/work/miniconda3/envs/QF9/lib/python3.9/site-packages/qutip/utilities.py", line 430, in _blas_info
    blas_info = config.blas_opt_info
AttributeError: module 'numpy.__config__' has no attribute 'blas_opt_info'

Failure occurs here,

https://github.com/qutip/qutip/blob/52d01da181a21b810c3407812c670f35fdc647e8/qutip/utilities.py#L340

which is kind of mysterious since line 339 explicitly checks that the ‘blas_opt_info’ attribute exists, and then fails at line 340 because the attribute doesn’t exist.
