Cave Overhaul

slime mold!

• added debug toggles for every cave type generated by the mod (accessible via cloth config/mod menu)
• removed obsolete and problematic reverse noise variant of caveworldcarverv12
• reworked 'old world caves' by clamping on Y axis to prevent vertical caves, in addition to other QoL changes
• removed non-functional 'cave_vertical_stretch' factor
• added highly experimental testing pipeline to allow slop agents to generate worlds and debug worldgen autonomously
