Support for White Box Tools

White Box Tools is an open source geoprocessing package made by the University of Guelph.
Its key benefit is its extreme speed, being able to process tools between 5 and 50 times faster than ArcGIS Pro. 
It would extremely beneficial if FME included an WBT transformer which could allow users to pass FME data to WBT and allow the user to select which WBT to run (there are hundreds). 
This would greatly expand the raster capabilities of FME, and include some functionality which is currently lacking in FME (viewshed)
