Adds bin/make-test-dbs, a Node.js script that builds geonames.sqlite3 and

zips.sqlite3 without downloading anything from geonames.org. It uses
cities-patch.txt as the main geonames data source along with minimal fixture
files in test/fixtures/ covering all 60 countries and 141 admin1 regions
referenced by cities-patch.txt.

test/fixtures/countryInfo.txt - 60 countries (19-field TSV, geonames format)
test/fixtures/admin1CodesASCII.txt - 141 admin1 regions (4-field TSV)
