small update for math domain error

- Finding points in polar areas that avoids dividing by zero errors

- Small errors in `overlap.py` to get overlap function working.

- Raise an exception if the shear is too high when trying to find the baseline affine

- Catch divide by 0 errors when getting the number of points to place in `centroids.py`
