I have improved the ListsOfState example.
The tableView(_:cellForRowAt:) delegate method can be called multiple times for the same indexPath, and in the current code, the observe(_:) method is executed multiple times for the same indexPath.
When the observe(_:) method is executed multiple times, the closure is called unnecessarily many times when the Counter model at the corresponding index is changed.
To prevent this, I have added the observation cancellation logic.
