Oi, time for another update :)

I've fixed a bunch of broken emitter mappings now (like campfire) as well as some voxel-related issues so this is more of a quality of life update.

Changelog:

- added voxel intersections for slabs- fixed block selection box in 1.17- added a bunch of voxel and lpv related settings- fixed campfires, redstone torches, fire and soul fire+lantern- fixed broken voxel color calculation- better onscreen emitter block brightness behavior- fixed samples per pixel above 1 being broken- fixed minor bleeding artifact caused by accumulation- potentially fixed red-box issue caused by the lpv- ninja fix: fixed wrong default value of the voxel volume depth cap
