+Add a new base class `StrictExtendableBaseModel`. This class is a subclass of
+`ExtendableBaseModel` and enforces strict validation by forcing the revalidation
+ of instances when the method `model_validate` is called and by ensuring that
+ the values assignment is validated. This class is useful when you need to
+ instantiate you model from a partial dictionary and you want to ensure that
+ any value assignment taking place after the instantiation is validated.

+    This is sometime not suitable when the data are changed after the
+    model is created or the model is created from a partial set of data and

+    The following parameters are added:
+    * revalidate_instances="always": model instances are revalidated during validation
+    (default is "never")
+    * validate_assignment=True: revalidate the model when the data is changed (default is False)
+    * extra="forbid": Forbid any extra attributes (default is "ignore")
