New Block Type: Steps (stair holes)

WHAT: What donut holes are to donuts, these blocks are to stairs. All the same functionality of a stair but the part of the block that is air becomes stair and the part that was stair becomes air. Put another way, 1/4 of a block instead of 3/4 of a block. They would still curve when placed next to each other, and use the same textures as all currently implemented stairs. WHY: Steps would intuitively complete the block set created by slabs, stairs and full blocks. Steps would allow more nuanced stair designs, allowing full blocks sutch as chiseled stone to be part of stairways, allowing stairways that run perpendicular to a slope, and allowing more control of landing shapes and sizes. Steps would also allow many other building tricks, such as to make pixel art, text, or details on floors and ceilings with a resolution four times higher than full blocks, or working with stairs to do the same things on walls. They could create small curbs and borders to mark paths, or produce slabs that are horizontally offset. HOW: Steps could be made very simply by taking a stair item and removing the slab-equivalent part from the hitbox and model, and then flipping the vertical orientation. All curving and connection functionality from stairs would work just the same for steps without changes, and would allow many advanced uses. Steps could be crafted using the inverse recipe of stairs (three blocks in the top corner), be made at a stonecutter, or even be a byproduct of crafting stairs.
