In the import library_of_congress Richmond, Virginia is hard-coded in the search terms.

Create two new environment variables for comma separated lists of cities and states to insert into search terms. Something like this:

DEPLOYMENT_CITIES=Riverside,Corona,San Bernardino
DEPLOYMENT_STATES=California

These will default to Richmond, Virginia of course.

Params will then look like

    states = "|".join(f"location:{state.lower()}" for state in STATES.split(","))
    cities = "|".join(f"location:{city.lower()}" for city in CITIES.split(","))
    params = {
        "fa": f"{states}|{cities}",
        "fo": "json",
        "c": items_per_page,
        "sp": start_page,
    }

This will become the basis of allowing variable cities and states for other deployments.
