Deepslate Fix

This data pack does three things. First, change the manner deepslate crafting works to be more akin its predecessor, stone. Second, allow players to rework stairs and slabs of stone materials (e.g. putting 4 diorite stairs in a crafting grid to craft polished_diorite_stairs). Third letting #stone_tool_materials be substituted for cobblestone in recipes and expanding what those materials are. These aims may be different enough to justify creating seperate data packs, but, because they tamper with the same recipes, for proper synergy they must needs be one. Crafting recipes should unlock automatically.

Deepslate
I've always found it strange that the new deepslate works so differently from stone. You can craft the cobbled variant straight into bricks without smelting it first and if you used silk_touch or spent time cooking the stuff you don't get anything out of it. Although this is akin to the new blackstone blocks which don't have a smelted variant deepslate, deepslate was obviously made to be like stone and I don't see why it should work so differently. My compromise is to require cobbled_deepslate to be smelted into deepslate for the crafting of deepslate_brick and deepslate_tile, but leave the recipe for polished_deepslate the same. After all, you don't need to cook andesite, diorite, or granite to polish those stones. Because I needed to remove some recipes in the game (the ones that turn cobbled_deepslate into deepslate_bricks) I had to create a recipe to cover it up. So if you put a petrified_oak_slab into a stonecutter you can turn it into an ordinary oak_slab. Your welcome, I had no idea that block existed before.

Reworking stairs and slabs
The number of recipes behind this simple addition is outstanding. I will not name every recipe, but I will give examples of 4 ways this affects crafting.
1. Crafting polished, cut, or bricked; slabs and stairs
e.g. putting 4 diorite stairs in a crafting grid to craft polished_diorite_stairs.

2. smelting cobbled or not yet smooth, slabs and stairs
e.g. smelting a cobblestone_slab in a furnace to create stone_slab.

3. stonecutting slabs and stairs into polished, bricked, or cut variants
e.g. putting a stone_slab into a stonecutter to create a stone_brick_slab

4. stonecutting stairs into their respective slab
e.g. putting a stone_stair into a stonecutter to create a stone_slab


#Stone Tool Materials
The first change is obvious. Make it so the blocks you can use to craft a stone_pickaxe can be used to make furnaces, hoppers, droppers, and so on. The second change expands what materials you can use to craft a stone_pickaxe and other stone things. I did not add any stones like some data_packs do and did not include andesite, diorite, or granite, like most do. The stones I chose serve some purpose.

In addition to, cobblestone, blackstone, and cobbled_deepslate, I added mossy_cobblestone, end_stone, sandstone, and red_sandstone

mossy_cobblestone because its made of cobblestone. I don't really understand why this can't be used already.
end_stone. I'm less confident on this one but I think since you can make bricks out of it that it should qualify. Mainly I think its important that a source of stone exists in every dimension.
sandstone. I chose sandstone for two reasons. First, since it can be smelted into smooth sandstone it has a stone equivalent like cobblestone does. Second it makes the desert more survivable. I realize this makes it so one can skip over the wooden_pickaxe step of the game, but that aspect particularly appeals to me. Digging up 12 blocks of sand isn't any easier than choping three logs and digging for stone. I like it when a game has multiple ways to begin.
red_sandstone. Same reasons as above

As for andesite, diorite, and granite, although these rocks make just as much if not more sense I figure they aren't necessary or missed and if minecraft wont include them neither will I.

If you disagree with my choices this is the easiest alteration to customize. Simply change the contents of the cobbled_stones tag in stone_fixture/data/minecraft/tags/items/cobbled_stones.json.
