opencv 5.0.0.93: AttributeError: module 'cv2' has no attribute 'CascadeClassifier'

Hi,

I was trying to use opencv, but the latest one pushed to pypi seems to be missing this method.

In [1]: import cv2
In [2]: c = cv2.CascadeClassifier('/home/helio/DEVEL/katten_away/model/haarcascade_frontalcatface.xml')
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[2], line 1
----> 1 c = cv2.CascadeClassifier('/home/helio/DEVEL/katten_away/model/haarcascade_frontalcatface.xml')

AttributeError: module 'cv2' has no attribute 'CascadeClassifier'

I enforced a fresh virtualenv to confirm the bug wasn't on my local packages.
