Hammers OG

First release of Hammers OG.

• Hammers and excavators in stone, iron, gold, diamond and netherite (no netherite on 1.12.2). They last 3 times as long as the pickaxe or shovel of their material and dig at 0.6 times its speed.
• Mining with one breaks a 3x3 square on the face you hit, through your own block breaking: tool wear, Fortune, Silk Touch and protection mods all work. Sneak to mine a single block.
• Only blocks the tool is made for and can harvest; much harder blocks and blocks with contents are skipped; the drops land in one pile; the tool stops at its last use.
• Settings in config/hammersog.properties.
