Boss Spawner Block

1. Introduction
   
   This is a custom BOSS spawn cage. It can't be said to only spawn BOSSes; it can spawn any living entity.
   
   The inspiration comes from the spawn box in Twilight Forest, and the functionality is quite similar. However, this one allows modification of the spawned creatures through a configuration file.
   
   2. Configuration
   
   Configure this in the bsb-common.toml file located in the .minecraft/config/ directory. Simply change the spawn egg ID after the "bossSpawnEgg" key.

Note: The spawner texture in this mod uses Xekr's red visibility resource pack, with the author's permission.
