Refresh the spawn atlas from a ServUO tree.

  node scripts/importSpawnAtlas.js [options]

  --servuo <path>  Use this tree for this run instead of the configured path.
  --force          Reimport even when the source files are unchanged.
  --approve        Apply a refresh that was staged for removing a facet.
  --reject         Keep the current atlas and dismiss the staged refresh.
  --status         Report atlas and source state; change nothing.

With no options this imports only if the tree differs from what is loaded.
