Implemented a geometry document field with a minimal `Geometry` enum. Now able to add that Geometry from GeoJSON parsed from a JSON document. Geometry is triangulated if it is a polygon, otherwise it is correctly encoded as a degenerate triangle if it is a point or a line string. Write accumulated triangles to a block kd-tree on commit. Serialize the original `f64` polygon for retrieval from search. Created a query method for intersection. Query against the memory mapped block kd-tree. Return hits and original `f64` polygon. Implemented a merge of one or more block kd-trees from one or more segments during merge. Updated the block kd-tree to write to a Tantivy `WritePtr` instead of more generic Rust I/O.
