GeometryContent mixin

An interface to write geometry data to format encoders and object builders.

This mixin supports specific simple geometry types defined by SimpleGeometryContent and geometry collections. It's possible that in future versions other geometry types are added.

Coordinate positions and position arrays are represented as coordinate value arrays of Iterable<double>.
