4.1 Compatibility

[digitalillusions]

Adjust code to fit the breaking change documented here: https://developer.blender.org/docs/release_notes/4.1/python_api/#mesh

Essentially: Dont set mesh.use_auto_smooth anymore, since mesh normals will be used automatically once they are set.

Minor Changes:

• Add code so that the addon can be debugged using the vscode blender extension.
• Don't throw an error if an attribute is of unexpected length, just ignore it.
