/**
 * Taking a zone's files as the game client's level editor sends them (ZoneFilePack) into the zone's set: unpacked,
 * made into a whole set, checked like any other set (ZonePublish) and applied (ZoneOverrideStore), or refused with
 * nothing written. A whole map is the zone's new set. One file replaces that file in the set the zone has and keeps
 * the rest; a set always has the zone's .luz, the client's own when none was sent or kept.
 *
 * Only reads the bytes it is given and files under the override folder: no connection, database or setting, so it
 * runs on a worker thread.
