Sable's 3d Ores

-Updated pack.mcmeta to better reflect compatible versions
-Updated pack.png (not terribly important but I'm an artist and I have to make things look cool alright)
-Fixed some ores being visibly darker than intended (especially diamonds)
-Rotated certain ore chunks to align with the grain of the stone
-Added a couple of extra cubes to diamond ore to accentuate the mineral structure (it look good I prommy)
-Adjusted iron ore cubes' texture to hopefully make it less muddy
