These both trim detail from the Nanite data that is stored to disk and can be used to optimize disk size after import. Should be a super useful tool late in production.

Changed fallback settings to be largely error based with new property FallbackRelativeError.
Nanite builder will now provide the LOD fallbacks for all autogenerated LOD levels which is far faster than generating them from scratch.

* First mesh is voxelized by tracing rays in every voxel
* Then voxel faces are clustered in parallel to build continuos cards. Clustering follows voxel distance, card ratio, density and other metrics
* Finally a specificied number of cards is selected per mesh (user parameter). This allows to tradeoff between coverage and runtime overhead
Other:
* Added surface cache coverage view mode for debugging coverage issues - r.Lumen.Visualize.Mode 6
* Fixed r.LumenScene.SurfaceCache.CardMinResolution to be able to go below 2

Added UI for changing minimum residency
Decoupled imposter data allocation from root page allocation
Removed convoluted logic around a page's dependencies including itself for legacy reasons
Made streaming of imposter data optional (r.Nanite.Streaming.Imposters)

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.
