Iris now supports custom structure grow events (trees). We will be adding new trees to this registry in the overworld in the coming updates. Any Iris Object Placement can now define saplings so when they are grown, it will place an the object instead of a vanilla tree (be sure to enable tree options in the dimension)
Added better decoration support for caves
Fixed an issue that was slowing down generation due to noise features
Fixed an issue where iris was false-detecting errors during studio init
