Emissive textures

[ryanlua]

This pull request adds support for subpacks and introduces texture set definitions for various ore and block textures in the fluoroscopy resource pack. The manifest is updated to support subpacks and a wider range of engine versions, while new .texture_set.json files provide PBR (Physically Based Rendering) metadata for multiple ores and blocks.

Manifest and Pack Structure Updates:

• Added two subpacks, "Outline Ores" and "Outline & Glow Ores", to the manifest.json, allowing users to select different visual styles.
• Lowered the min_engine_version requirement in the manifest.json from [1, 21, 130] to [1, 21, 110] for broader compatibility.

New Texture Set Definitions:

• Introduced .texture_set.json files for the following blocks, each specifying PBR metadata:
  • Overworld ores and blocks: coal_ore, copper_ore, diamond_ore, emerald_ore, gold_ore, iron_ore, lapis_ore, gilded_blackstone, nether_gold_ore, ancient_debris_side, ancient_debris_top. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
  • Deepslate variants: deepslate_coal_ore, deepslate_copper_ore, deepslate_diamond_ore, deepslate_emerald_ore, deepslate_gold_ore, deepslate_iron_ore, deepslate_lapis_ore, deepslate_redstone_ore. [1] [2] [3] [4] [5] [6] [7] [8]
