Huge update

• Completely revamped settings
• Added the ability to set custom particle textures.
• Added the ability to set custom beam/particle display settings for each item via NBT
• Expanded support for custom item rarities. Now rarities can be defined through a resource pack in the file assets/lootbeams/custom_rarities.json
• For custom rarities through JSON, beam/particle display settings can be specified
• These rarities can be applied to an item by assigning it the NBT custom_rarity_id (String)
• If both custom_rarity_id and custom_rarity are set, custom_rarity will take priority

Below are some examples of beam configuration with the new features.
