Nyf's Spiders Optimised for 1.20.1

This mod is derived and built from the code found here: https://github.com/Nyfaria/NyfsSpiders/tree/1.20.x and as per the page as at date of access adheres to the CC0-1.0 license.

It will likely only remain as an option for 1.20.1, and under the assumption that additional game breaking or behaviour invalidating bugs are not found as its reason for existing is inclusion in the Au Naturel modpack, though you are free to use it elsewhere as desired.

It represents an attempt to come to a working solution after some frustratingly long sessions with spark profiler, observable, and using claude code to document, summarise, modify and understand the original code base, and then come to working bugfixes and optimisations to make Nyf's spiders sufficiently performant while attempting to not sacrifice the subjective player experience of spiders that move and hunt the player (and other objectives) through the total 3d space rather than being anchored to the ground like in original minecraft.

Nyf's spider's is a fantastic mod, and one of the most important in the scope of Au Naturel as spiders are one of the primary dangerous mobs that represent the hostile environment and make night time and caves scary. But there's always been some lingering performance bugs and issuse and it always easily used the most tick resources of any of the mods in Au Naturel.
