Functions to read and write geometries in WKB and WKT formats.

The WKB format is specified in the OGC Simple Features for SQL specification. This implementation supports the extended WKB standard for representing 3-dimensional coordinates. The presence of 3D coordinates is signified by setting the high bit of the wkbType word. Empty Points cannot be represented in WKB; an IllegalArgumentException will be thrown if one is written. The WKB specification does not support representing LinearRing, they will be written as LineString
