if (bbox_intersection_area(ba, bb) / bbox_area(ba)) > 0.8: ZeroDivisionError: float division by zero

I'm encountering a ZeroDivisionError: float division by zero error in camelot-py when using the functions bbox_intersection_area and bbox_area. This error occurs under certain conditions, likely when the bounding box area (ba) is zero.

I did a quick fix/hack to circumvent the error by skipping over the area check if ba is singular (area is zero):

~/.pyenv/versions/3.11.3/lib/python3.11/site-packages/camelot/utils.py: Line 375:

            if bbox_area(ba) > 0 and bbox_intersect(ba, bb):
                # if the intersection is larger than 80% of ba's size, we keep the longest
                if (bbox_intersection_area(ba, bb) / bbox_area(ba)) > 0.8:
                    if bbox_longer(bb, ba):
                        rest.discard(ba)
