Make it sense to add polyline encoding / decoding to this library? Was for example [part of maplibre-java](https://github.com/maplibre/maplibre-java/blob/db35dfd06f9d671bfda1fd5771b478772c872631/services-geojson/src/main/java/org/maplibre/geojson/utils/PolylineUtils.java#L39) - **If yes**, I will create a PR, - **If not**, I will create a separate library ;-) What do you think @sargunv @jgillich?
