If a repeat teleporter boss would spawn, a different available boss for that stage will be chosen. If there are no other available bosses, a repeat boss will be allowed.
Config for amount of previous stage bosses to compare against current boss.
Future Plans
When there aren't any other available bosses, add feature to use oldest boss in the queue
