Dev news : 1.17 style ores: redstone and coal + deepslate tweak (Patreon)

I started migrating the VanillaccurateXXL ores to the 1.17 styles (AKA the ones with different patterns so color-blind folks have fewer issues figuring out which is which).

The first two I did are coal and redstone. 

I also tweaked deepslate a bit to bring it a tad closer to vanilla. It seemed too sharp and deep, I wanted it a bit more round overall. Seems to look better now.

Enjoy !
