Andrew's Datapack Utils

Added a scaling system for the calculator, to scale the output passed to execute store result added sin, cos, tan, clamp, and modulo as operations usable by the calculator added aputils pathfind, which can make any mob go towards a set position or entity (does not track position changes of provided entity, only goes toward where it was when the command was run. to constantly update it, make it run every tick using a repeating command block or datapack.) added aputils target, which makes any non-passive mob target an entity (needs to be living, so stuff like item entities won't work). This does not respect a mob's view range or an entity's targetability (example, creative mode players will still be targeted by this command, although the mob will lose interest once it gets to the player)
