Spear, useing diffrent materials for the tip

Add spears,with the tip being made with the usual materals weapons use [wood,stone,copper,iron,gold,diamond,netherite], (how i think they should be crafted craft:1 make a spear handle with 3 sticks in a crafting table, 2 put the spear handle under 1 selected material) spears have the option to be either ranged, or used as a melee, diffrent materials effect the range and attack speed, for melee spears are slower than swords,mbut have increased range with better knockback
