This patch replaces the vanilla collision code for both block and entity collisions with faster implementations by JellySquid, used originally in her Lithium mod. Optimizes Full Block voxel collisions, and removes streams from Entity collisions Original code by JellySquid, licensed under GNU Lesser General Public License v3.0 you can find the original code on https://github.com/jellysquid3/lithium-fabric/tree/1.15.x/fabric (Yarn mappings) Ported by Co-authored-by: Zoutelande <54509836+Zoutelande@users.noreply.github.com> Touched up by Aikar to keep previous paper optimizations
