Use case

When using DynamoDBRecord class, the values for old_image and new_image are represented as Dict[str, AttributeValue]. This representation is sufficient when the data parsed is simple and does not contain nested maps/lists.
But when the data parsed contains nested maps/lists, then it becomes hard to get to the data that AttributeValue represents.
One would need to recursively parse the AttributeValue objects in the nested dicts to get to the underlying data.

Solution/User Experience

Using a deserializer similar to the TypeDeserializer provided by boto3 (link to code), one would be able to convert image to a Python dict where the values would be built-in Python types.
