Could the get_children() method return an empy list if the Py5Shape object has no children?

I know I could check if the get_child_count() is not zero, but it would make life easier sometimes just to use get_children() and get an empty list...

>>> shp.get_child_count()
0

>>> shp.get_children()
Traceback (most recent call last):
  File "PShape.java", line 2091, in processing.core.PShape.getChildren
Exception: Java Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/villares/thonny-env/lib/python3.12/site-packages/py5/shape.py", line 47, in decorated

  File "/home/villares/thonny-env/lib/python3.12/site-packages/py5/shape.py", line 3231, in get_children
    return self._instance.getChildren()

Hmmm, I agree, it should return an empty list, not throw an exception, and a Java one at that. Is this for a GROUP type shape that happens to have no children, or a non-GROUP shape? For both, I think this should return an empty list. I will open an issue for this.

This became the fixed issue #501
