the ESRI shapefile depends on whether the coordinates are clockwise or counterclockwise to determine internal and external polygons. This library seem to does not have a function to determine whether the coordinate-squeue is counterclockwise. I have implemented one using pure Golang, hoping to be helpful to you.
