> The SourceOperator has some boiler plate code taking the bytes out of the {{ListState<byte[]>}} and applying the {{SimpleVersionedSerializer}} to turn them into the splits.
> This repeated code can be simply encapsulated in a utility class {{SimpleVersionedListState<T>}} which wraps a {{ListState<byte[]>}} and applies the serialization and de-serialization.
