Subject: [Zurich] Use new LV95/CH1903+ geocoder and base map tiles

 - Use new `getLocation95` method for geocoding addresses
 - Replace Coordinates::CH1903 with Coordinates::CH1903Plus
 - Refactor Map::Zurich to use WMTSBase instead of duplicating code
 - Slightly refactor map templates to make using custom WMTS tiles easier
 - Use correct sizes for marker pins on maps

Closes mysociety/FixMyStreet-Commercial#769.
