Feature description

Right now if a column has a composite type, it is generated as Column(NullType) with Python type Any. With CompositeType from sqlalchemy-utils maybe it's possible to generate code for composite types.

Use case

There would be somewhat nicer syntax for setting and getting columns with composite types, and more information from the schema would be represented in Python form.
