Computes summary statistics for a delineation object and returns them as
a structured list of class summary.delineation. Delineation layers are
reported with their area (in km²). For segments, the number of features
and mean area are also given. Base layers are reported with feature counts;
river_centerline as total length (in km) and river_surface as area
(in km²).
