Detailed Description

A non-owning, immutable view of a geometry column.

A geometry column is GeoArrow compliant, except that the data type for the coordinates is List<T>, instead of FixedSizeList<T>[n_dim]. This is because libcudf does not support FixedSizeList type. Currently, an even sequence (0, 2, 4, ...) is used for the offsets of the coordinate column.
