AttributeError: 'Polygon' object has no attribute 'shape_nfps' in addShapeAsHole() #27
Description
I am encountering an AttributeError when using optimiser.addShapeAsHole(). The error indicates that the Polygon object being processed does not have the shape_nfps attribute, suggesting it's a standard shapely.geometry.Polygon object rather than the extended WasteOptimiser Polygon class.
Full Traceback:

newhole.shape_nfps = defaultdict()
AttributeError: 'Polygon' object has no attribute 'shape_nfps'
(Note: Line number 262 is where the attribute assignment is attempted.)
Steps to Reproduce:
Initialize the WasteOptimiser API.
Attempt to place shapes using self.api.placeAllSelectedShapes() or directly call self.optimiser.addShapeAsHole() with any valid shape.
Expected Behavior:
The addShapeAsHole method should successfully process the shape, and the newhole object should be an instance of the custom WasteOptimiser Polygon class, possessing the shape_nfps attribute.
Actual Behavior:
An AttributeError occurs because the newhole object is a standard shapely.geometry.Polygon, which lacks the shape_nfps attribute. This happens even when self.optimiser.convex_hull is set to False, indicating a more fundamental issue with the Polygon object instantiation within WasteOptimiser.
Environment:
Operating System: Windows11
Python Version: 3.8.7, 3.9.13, 3.11.9, 3.13.8
