FR: Generate __slots__ for objects

By default, Python uses a dict to store the fields of a class. This allows for fields to be dynamically added to an object at the cost of runtime performance and memory usage.
We can avoid the runtime costs by definin __slots__ in our objects. This tells Python to only allocate enough space for the predefined set of fields.
