XYZ isn't optional to calculateBounds
We can't toWKT 3D bounds, so you only get 2D. Add a toBox() method that creates a PostGIS-compatible BOX or BOX3D
only ever output 2D WKT from Bounds
try reprojecting with the old Z values if we failed with the current Z values
add a binary_to_hex_stream method
more soci writer stuff
