HTP CIT Resewn Optimizer

CIT Resewn has two issues in large modpacks. First, it re-evaluates custom item textures every frame even when nothing has changed — this causes unnecessary CPU usage when browsing large inventories or EMI item grids. Second, it leaks over 1 GB of RAM per session by allocating objects into every ItemStack that are never freed.  

This is a patch for https://modrinth.com/mod/cit-resewn

What does HTP CITOptimizer do?

Caches CIT evaluation results so repeat lookups are skipped, and fixes a massive memory leak.
Significantly reduced GC pressure from eliminated per-frame allocations. 
Lower CPU usage when browsing large inventories or EMI item grids.  

Your client will no longer freeze, crash, or lag after hours of gameplay requiring a restart due to CITResewn. 

We were experiencing memory climbing steadily until it hits the heap limit causing stutters multiple times per day most noticable when relogging on servers.
