1.17.1

I wanted to just add some stuff, but found a big bug.
+ Easier config reloading
+ Config presets
+ 9-ray occlusion evaluation for blocks (corners + middle) (feels better, kinda like can see vs can't see)
+ v1.0 occlusion preset. idk if worth it.
- reflection ray scattering is now completely and fairly random. causes some inconsistencies idk if keep it.
- fixed severe raytracing "bugs". Really, minecraft just didn't output correct position from ray tracing, so i calculated it myself.
- merged a pull request to get rid of autoconfig
~ Reflection rays still can fit through block ribs somehow. Just increase their amount to hear sounds more consistently.
