Implemented a `Surveyor` that will evaluate the bounding boxes of a set
of triangles and determine the dimension with the maximum spread and the
shared prefix for the values of dimension with the maximum spread.
Implemented byte-wise histogram selection to find median values without
comparisons, enabling efficient partitioning of spatial data during
block kd-tree construction. Processes values through multiple passes,
building histograms for each byte position after a common prefix,
avoiding the need to sort or compare elements directly.
The `triangulate` function takes a polygon with floating-point lat/lon
coordinates, converts to integer coordinates with millimeter precision
(using 2^32 scaling), performs constrained Delaunay triangulation, and
encodes the resulting triangles with boundary edge information for block
kd-tree spatial indexing.
It handles polygons with holes correctly, preserving which triangle
edges lie on the original polygon boundaries versus internal
tessellation edges.
Encodes triangles with the bounding box in the first four words,
enabling efficient spatial pruning during tree traversal without
reconstructing the full triangle. The remaining words contain an
additional vertex and packed reconstruction metadata, allowing exact
triangle recovery when needed.
