Add support for MBTiles maps #161

Closed OgreTransporter closed 1 year ago

OgreTransporter commented 2 years ago

This PR adds a MapProvider for MBTiles files.

Demo files are available at https://ftp.gwdg.de/pub/misc/openstreetmap/openseamap/charts/mbtiles/. Sample code:

            GMapProviders.MBTilesMap.Open("OSM-OpenCPN2-Germany-NorthEast.mbtiles");
            this.MainMap.MapProvider = GMapProviders.MBTilesMap;
            this.MainMap.MinZoom = GMapProviders.MBTilesMap.MinZoom;
            this.MainMap.MaxZoom = GMapProviders.MBTilesMap.MaxZoom;
            this.MainMap.Zoom = GMapProviders.MBTilesMap.MaxZoom;
            this.MainMap.Manager.Mode = AccessMode.ServerOnly;
            this.MainMap.CenterPosition = new PointLatLng(52.516280, 13.377695);

This variant allows to use offline maps.
