Old Ore Textures (With Copper)

### I disliked the new ore textures, so I made a pack that changes them back to how they were pre-1.17.  Image of all the changed blocks and ores I also included my own imagining of what copper may have looked like if it used the old ore texture style. Changes: - Reverts all ore textures to pre-1.17 - Reverts deepslate variants - Changes copper to a custom texture that I think fits with the old ores **Feedback is welcome!**
