* Fixed an issue with HDRIs not generating proper PMREMs over multiple viewer instances
* WIP on makign the world tree multiple instanced
* The WorldTree is no longer static. Each viewer has it's own instance and it hands it over to whoever needs it.
* Fixed an issue with filtering and the new non-static tree. Also removed the 'root' key from the NodeData structure since it's not needed
* Added an guard when building batches for situations where all render views have invalid geometries. This generally means there is somethign wrong with the stream itself
* multi-viewer css fixes

* The ObjectLoader and ViewerObjectsLoaders are disposed upon loading complete.
* Added viewer parameter for keeping or discarding original geometry data. Defaults to discarding it. WIP on mesh and point cloud implementation for actual discarding it
* Geometry data from raw nodes is now disposed after building their reder views
* Removed raw geometry data from points and lines
* Removed the float64 array which was persisted pointlessly by the section plane outlines feature. Also fixed a bug for this feature regarding resizing the point buffer and RTE
* Implemented BVHs in local space, relative to world origin. This cuts down on it's redundant memory footprint by half
* Implemented SpeckleMeshBVH which completely hides the RTE-related transformations that we're making to reduce memory footprint.
* Added some clarifications to the SpeckleMeshBVH class
* Implemented async walk for the world tree. Implemented asyn render tree building and async batch building. Implemented progressive loading
* WIP tree walk async that actually works using a generator
* Async walking now properly works and can be interrupted
* Properly working async walk
* Added loadObjectAsync function in the API which should be used if stream loading needs to be cancelled and for 'progressive' loading. Added a priority argument to the loadObjectAsync and to walkAsync functions which makes the async-iness so to speak configurable.
* Refactored the sync and async subtree batch building to remove duplicate code. Changed some logs for better clarity
* Fixed an issue with point clouds and material creation
* Added a verbose flag in the viewer params. Default is false and it's equivalent to the ERROR level
* Piggybacked the original pointer event into the SelectionEvent
