Craftable diamonds mod

 I created a simple mod that makes the diamond manufacturable through the crafting table with
9 coal blocks and obtainable by melting a block of coal obtaining the only thing that is not a
recipe: the diamond nugget, it behaves like iron in fact if you try to melting a diamond
pickaxe you will get a diamond nugget just like the iron one, I also made the charcoal
craftable with 4 pieces of charcoal, then I added the "small diamond" advancement when
you get the diamond nugget for the first time
