/**
 * Helper function for installation and upgrades.
 *
 * This function inserts data into the weather_places table.
 *
 * The data file lists one table entry per line. Fields are separated
 * by tab stops. The format is as follows:
 *
 * GeoID
 *   Primary key, string. Currently supported keys are:
 *   - GeoNames ID, prefixed with geonames_
 *   - Sentralt stadnamnregister ID, prefixed with ssr_
 *   (tab stop)
 * Latitude
 *   -90 .. 90, Positive values for north, negative for south.
 *   (tab stop)
 * Longitude
 *   -180 .. 180, Positive values for east, negative for west.
 *   (tab stop)
 * Country
 *   (tab stop)
 * Name
 *   (tab stop)
 * Link to yr.no weather forecast
 *   (newline)
 *
 * To save space, the link to the actual yr.no URL has been shortened.
 * Every URL starts with "https://www.yr.no/place/", followed by the
 * country.
 *
 * In the country's name, every whitespace gets replaced with an
 * underscore, all other characters are kept as they are. The only
 * exception is the last dot in the following country:
 *
 * "Virgin Islands, U.S." -> "Virgin_Islands,_U.S_"
