Breaking changes

sqlachemy extension no longer requires to use items_transformer when selecting scalar field:

This code is no longer valid:

paginate(session, select(User.name), transformer=lambda items: [{'name': item} for item in items])

The correct version now is:

paginate(session, select(User.name))
