lots of environment changes! (clean switching + new desert biome! 🏜️)

–

Changelog

added ways for the player to detect which chunk and biome it is on
main (root) node script that runs these player functions and also pulls the biome information
added an environment color variable to the biome data resources, and added appopriate colors for each biome
root node uses tweens to make the environment color correct upon switching biomes
desert biome! (just a cactus)
added two new contents to the wastelands
temporarily made the eye monster blue to look native to glacier biome

edit eye monster fsm
add variants to the eye monster (my only enemy right now) that are native to each biomes by changing albedo color like the temporary change I just did
make chunks spawn enemies automatically like minecraft
use hdr to make a better sky and environment in general

i think it’s really coming together now, and this project now has the highest amount of hours so I guess that’s nice i like the minion thing
