* WIP start including rotation data
* Fix option to use orientation data or not
* Renames to reflect that points are no longer billboarded (at least not always)
* Increase max value for scale factor
* Fix correct scaling for tully and deep sky objects
* Remove the old RenderablePlanesCloud, we don't need it anymore
* Add unit handling for size scaling from data values
* Clarify some documentation about the points being rendered as planes
* Update datasets to the new ones on the server
* Use quaternions for orientation instead of vectors (simplifies interpolation and requires less data)
* Make interpolation of orientation work
* Fix size for deep sky objects being too small due to data being radius rather than diameter
* Add IsRadius flag for deepsky
* Update asset versions (major number update, due to breaking changes)
