/**
 * Convenience method to add a ticket that is backed by an AABB.
 * <br>
 * If you don't want to water the region anymore, call {@link SimpleTicket#invalidate()}. Also call this
 * when the region this is unloaded (e.g. your TE is unloaded or the block is removed), and validate once it is loaded
 * <br>
 * The AABB in the ticket is immutable
 * @param world The world where the region should be marked. Only server-side worlds are allowed
 * @param aabb The region where blocks should be watered
 * @return The ticket for your requested region.
