Make sure entities aren't created when using new merged geometries

[kfarr]

it appears that building entities are being created?

Instead perhaps something like this?

Thanks, I've pushed 51b7dcdb to avoid this and clean up leftovers.

The mergeGeometries vs mergeBufferGeometries seems to be a dependency topic. In 979b918 I've added an (unversioned) dependency on BufferGeometryUtils, which apparently differs from the version you're using. Would the following help in addBuildings?

const mergeGeometries = THREE.BufferGeometryUtils.mergeBufferGeometries ? THREE.BufferGeometryUtils.mergeBufferGeometries : THREE.BufferGeometryUtils.mergeGeometries;
let geometry = mergeGeometries(geometries, false);
