Bounding box property WSIAnnotations class errors when loading multipoint.

[Dafidofff]

Describe the bug
When calling the property bounding_box of the WSIAnnotation class return an the following attribute error
AttributeError: 'Point' object has no attribute 'exterior'

To Reproduce

from pathlib import Path

from dlup import SlideImage
from dlup.annotations import WsiAnnotations


slide_path = Path("/data/datasets/NKI/slides/1285/195551/T17-06278 A1 PD-L1 (22C3).svs")
anno_path = Path("/data/datasets/NKI/data/annotations/studies/slidescore_1285/v20230210-0/annotations/wsong@ellogon.ai/195551/Lymphocytes.json")  # --> multipoint annotation
dlup_slide = SlideImage.from_file_path(slide_path)
dlup_anno = WsiAnnotations.from_geojson(anno_path)

# wsi = dlup_slide.read_region(location=(0,0), size=dlup_slide.size, scaling=1.0)
anno_in_region = dlup_anno.read_region(coordinates=(0,0), region_size=dlup_slide.size, scaling=0.01)
print(anno_in_region)

bounds = dlup_anno.bounding_box

Gives the following error:

Traceback (most recent call last):
  File "/homes/dwessels/LightningGon/test_multipoint.py", line 41, in <module>
    bounds = dlup_anno.bounding_box
  File "/homes/dwessels/.cache/pypoetry/virtualenvs/lgon-WMDuiRwL-py3.10/lib/python3.10/site-packages/dlup/annotations.py", line 321, in bounding_box
    curr_bboxes = self[label].bounding_boxes
  File "/homes/dwessels/.cache/pypoetry/virtualenvs/lgon-WMDuiRwL-py3.10/lib/python3.10/site-packages/dlup/annotations.py", line 227, in bounding_boxes
    data = [np.asarray(annotation.envelope.exterior.coords) for annotation in self.as_list()]
  File "/homes/dwessels/.cache/pypoetry/virtualenvs/lgon-WMDuiRwL-py3.10/lib/python3.10/site-packages/dlup/annotations.py", line 227, in <listcomp>
    data = [np.asarray(annotation.envelope.exterior.coords) for annotation in self.as_list()]
AttributeError: 'Point' object has no attribute 'exterior'

Expected behavior
Give back then bounds of the point annotations, something like the following:

points = dlup_anno._annotations["Lymphocytes"].as_list()
bounds = [point.bounds[:2] for point in points]

Environment
dlup version: 0.3.23
How installed: via Git on branch #148
