Description
Hello, this port is very nice overall but it would be nice if it could have the difference and union transform operations. We have a product using turfJs and we have a new product that is processing a shape file and converting it to t geoJson. Part of this is calculating the area, we want to match the area calculation algorithm to match our js implementation but the lack of the difference and union operations is preventing us from doing so at the moment.

Research direction
Start by locating the existing Turf and GeoJSON operation entry points in the Java SDK, then compare them with the Turf.js difference and union behavior. Use the shape-file to GeoJSON and area-calculation use case as the acceptance context; done means both operations are available and produce matching results for that workflow.
