Deduplicate foward/reverse geometries

Changes the internal representation of compressed geometries to be a
single array shared between forward and reverse geometries that can be
read in either direction. Includes a change on
extractor::OriginalEdgeData to store via_geometry ids that indicate
which direction to read the geometry for that edge based edge.

Closes #2592
