UnitVectorEncoding

Work-In-Progress compact Unit-Vector encoding from float3 to Octahedron (octant) form

Scalable memory footprint
- 2-axis Octant encoding to Int8[2], Int16[2], Float16[2], Float32[2]
- Trade-off precision for size and/or speed
Fast
- TODO: Benchmarking

Potential uses

SDF (Signed Distance Field) geometry rendering and storage
