I believe this covers both #647 and #719.
Moved sqlalchemy stubs from 2 to 2and3;
changed sqlalchemy/util/compat.pyi:37 to be of type typing.Text;
added incomplete stubs for sqlalchemy.orm.utils and slqalchemy.sql.elements.ColumnElement.
* Update annotations for requests.api.get
Argument params of requests.api.get accepts not only dictionaries of str, str pairs, but dictionaries and tuples of various types.
