Soul Sandstone

I think the look of sandstone is nice, but limited colour-wise. The current two sandstones are beige and orange, which are two very light colours that will not work well in darker builds/themes. Soul sand is a nice, dark brown colour that would work well as sandstone. Soul sandstone should be able to be crafted into stairs, slabs, chiseled (maybe the design could have a large soul like the ones on the soul sand block?) and smooth/cut variants, just like the current two sandstones. Perhaps soul sandstone could even trigger the Soul Speed enchant allowing for increased speed on staircases, slab-bridges, etc.
