Changes:

Upgrade to property-graph@v2
Fixes #954
Progress on #1133
🚀 Improved performance when processing large, complex scenes
‼️ Breaking change for authors of extensions. One-to-many references now require use of the RefSet, RefList, or RefMap types. See updates to core classes and extensions in this PR.

Note - the only bench mark that really improves with this PR is 'flatten.bench.ts', but real-world testing on larger scenes like PlantComplex showed large improvements on join and dedup operations as well. Mainly this allows faster disposal of objects, which was previously not well optimized for scenes with many nodes or accessors.
