Pages can now refererence data from the parent page.
Page transcoding is now batched based on page dependencies.
Removed Nanite's LZ container for platforms that don't have hardware LZ. Rely on iostore compression instead. ~4% disk saving. 32mb system memory saving from temp buffer.
Better integer-based UV quantization code similar to new position quantization.
Got rid of remaining old position quantization code.
Reduced float4s per cluster from 8 to 6. ~2% memory density.
Added BitStreamReader support for reading from UAV. Needed to reference parent data.

The scheme solves issues where meshes would no longer align properly after converting them to Nanite. It also solves the precision issues in clusters with triangles of non-uniform size.
By default the precision is heuristically selected by Nanite, but the user also has the ability to override with an explicit precision to solve issues or optimize for disk size.
Clusters store the coordinate components using the minimal number of bits required to span the range of values in the cluster.
Apart from fixing issues, the default quality seems no worse than before and is typically ~5-10% smaller than before.
Added Position Precision to the top left of Mesh viewer along with the other mesh stats.
Added Position Precision dropdown to Nanite import settings.
Added debug mode "r.nanite.visualize PositionBits" that shows the vertex position bit sizes for clusters.
New quantization code now updates float positions and cluster bounds to reflect the quantized coordinates.
