Refactoring and optimisations

[juntyr]

• strengthened all Habitat-derived cog pre-conditions s.t. Locations and IndexedLocations must be habitable, not just within bounds
• removed the IndexedLocation index hack, use the full u32 instead
• removed the GlobalLineageReference representation hack, use the full u64 instead
• optimised the WrappingNoiseHabitat to use wrapping 2d noise instead of 4d noise
• pulled in a better EventBuffer from #230
• changed the PackedEvent representation to retain its packed size despite the removed hacks
