MAINT: TF crashes on import for Apple M1

[bsipocz]

Locally tensorflow crashes at import time (cell no2), tried python 3.9 & tf 2.9.1 and python 3.7 & tf 1.13.1.

OTOH the cell runs without issues both on colab (python 3.7 and tf 2.8.2) and on binder (3.7 & 2.9.1), so my first guess is it maybe some M1 issue. If that's the case we need to give some specific installation instructions to the users.
If the crash is due to some other issues we probably need to pin and use specific version combinations.

In the meantime, there seem to be third-party binaries both as wheels on pypi and conda-forge. For the former, I run into pip install issues and haven't yet tried the conda route.
