/**
 * This little Tampermonkey script resizes the map on openstreetmap.de to full page size and
 * hides the annoying layer selector. It gives the possibility to inital set the coordinates
 * and zoom level by specifying it in the loction hash:
 * https://www.openstreetmap.de/karte.html#<Zoom>/<Latitute>/<Longitute>
 * Example for the center of Germany:
