Import error using SQLAlchemy v1.4

uszipcode requires sqlalchemy as a dependency; but no version is specified so it will always install the latest version.

SQLAlchemy==1.4 was released yesterday. One of the changes is that

from sqlalchemy.ext.declarative.api import DeclarativeMeta

used on uszipcode-project/uszipcode/pkg/sqlalchemy_mate/pt.py raises an import error. However, on uszipcode it is being ignored by a try except call.

So, a fresh install of uszipcode will produce a ImportError: cannot import name 'SearchEngine' when trying to import the SearchEngine.

To Reproduce

Steps to reproduce the behavior:

1. Create a fresh virtualenv
2. Run pip install uszipcode
3. Try to run from uszipcode import SearchEngine on the shell
4. See error

Expected behavior

It should raise a versions error or something more telling; the try except being used on uszipcode-project/uszipcode/pkg/sqlalchemy_mate/__init__.py is reducing the obtained feedback and it may be confusing to new users.

Thank you,

@rv-krosenberg you may run pip install SQLAlchemy==1.3.23 and use that SQLAlchemy version in your project

@aaronsmith1234 by the way, I made this compatible to sqlalchemy<1.4 as well by adding a try, catch around your code. Thank you for your contribution
