Platinum

• Changed textures of platinum blocks to look better
• Changed textures of platinum ingots and raw platinum to fit new block textures
• Changed spyglass and brush to fit new platinum textures

v1.4 was skipped due to it having an outdated pack.png. I saw no reason to include v1.4 on Modrinth as I already fixed the problem, and I am trying to keep current version numbers the same between Curseforge and Modrinth.
