[issue22098] Behavior of Structure inconsistent with BigEndianStructure when using __slots__

[Florian Dold]

New submission from Florian Dold:

Habimg __slots__ = [] on a class inheriting from ctypes.Structure prevents undefined fields from being set, as expected.

When inheriting from ctypes.BigEndianStructure, however, it is possible to set undefined fields.

See the attached file for small test case for the behavior.
