Cesium for Unreal 2.7.1 Release

Cesium for Unreal v2.7.1 is now available. Highlights of the release include:

Improved collision and line tracing against tilesets by working around an overly aggressive degenerate triangle check in the Chaos physics engine.
Fixed a bug that could cause a bad_any_cast exception when trying to access glTF extensions on non-Windows platforms. This commonly popped up when loading tilesets with metadata.
Fixed a bug that caused the GetInteger64 functions on CesiumMetadataValue, CesiumPropertyArray, and CesiumPropertyTableProperty to always return the default value on non-Windows platforms.
Fixed issue with UCesiumGlobeAnchorComponent::GetEllipsoid that caused compilation errors on some machines.

Check the Cesium for Unreal release and the Cesium for Unreal Samples release for the full list of updates.
