* This function is analogous to minetest.place_schematic, but places a schematic onto the
specified VoxelManip object `vmanip` instead of the whole map.
* Returns false if any part of the schematic was cut-off due to the VoxelManip not
containing the full area required, and true if the whole schematic was able to fit.
* Returns nil if the schematic could not be loaded.
* After execution, any external copies of the VoxelManip contents are invalidated.
