Remove usage of scipy.stats.binom_test

[NicolasHug]

It's deprecated. Not super urgent at we only rely on it in the tests.

  /work/test/test_transforms.py:1437: DeprecationWarning: 'binom_test' is deprecated in favour of 'binomtest' from version 1.7.0 and will be removed in Scipy 1.12.0.

(Also noticed this warning)

  /work/ci_env/lib/python3.8/site-packages/scipy/stats/_discrete_distns.py:77: RuntimeWarning: divide by zero encountered in _binom_pdf

Hi @pmeier, how to proceed on this ?

[pmeier]

As the warning implies, the function scipy.stats.binom_test is deprecated and scheduled for removal in scipy==1.12. Current version is scipy==1.10 so we have a little time, but we should act on it nonetheless.

The warning also gives you the upgrade instructions: you only need to replace binom_test with binomtest. I've linked all usages of the function in my comment above.
