Boulders, Rocks and Pebbles

I like having stone and deepslate drop rocks, what i dont like is having to download a dependency that adds a bunch of other things, so i made this.

This is ported over from my main mod, The Wrought Project, for those who want just this and nothing else. 
It doesnt even add naturally generated rocks!

When stone/deepslate is broken, a singular rock will guarantee to drop, with a 50% each of three more as well.
Use four rocks to craft cobblestone.

This mod hasnt been tested outside 1.20.1, but should (in theory) work just fine.
