Creating an Enum column

Movies have a fixed status vocabulary like Released, Rumored, Post Production, and so on. Since the allowed values are known upfront, an Enum is a better fit than Categorical: it adds validation that catches any unknown status before it pollutes the pipeline.

movies is still available, along with a pre-defined status_enum listing every allowed value.
