Iris has a new pregenerator, Pregenerator2 which will allow us to expand into cooler things through pregens such as multiple servers contributing to a single pregen
The new pregen system is safer at installing headless chunks & fixes a lot of mca problems that existed before
Fixed a critical issue that caused parallax chunks to be cut off
Fixed a critical issue that caused an alarming amount of memory to be allocated on dimensions without a parallax layer
Fixed another critical memory issue that should overall improve iris's performance
