Title: fix thread contention issues and VS crash on domain server shutdown and restart

- better read/write locking on SVO file load vs VoxelSendThread behavior
- waits to serve voxels to clients until SVO is loaded
- adds Voxel File Load stats to the VS server stats page
- clears node list on ::run() shutdown to properly shut down voxel send threads to prevent crashes on restart of assignment
