Subject: [PATCH] Carpet-Fixes: Use optimized RecipeManager

Original license: MIT
Original project: https://github.com/fxmorin/carpet-fixes

Optimized the RecipeManager getFirstMatch call to be up to 3x faster
This is a fully vanilla optimization. Improves: [Blast]Furnace/Campfire/Smoker/Stonecutter/Crafting/Sheep Color Choosing
This was mostly made for the auto crafting table, since the performance boost is much more visible while using that mod
