      Creates a new FeatureSourceTupleIterator

      Parameters:
      featureSource - a FeatureSource to pull features from
      query - a query to use when building the SimpleFeatureIterator.
      sridSet - the sridset to use for mapping CoordinateReferenceSystems to SRID (Geometry.getSRID())
      type - the struct that Tuples will use.
      Returns:
      a new FeatureSourceTupleIterator
