Firework Capsules has had a massive overhaul going into the 2.0 update!

Stickers are now ENTIRELY data-driven

• Stickers are now all under the fireworkcapsules:sticker id.
• Sticker mechanics are now defined under the fireworkcapsules:sticker_explosion data component.
• New stickers can be created using ONLY a resource pack (with optional datapack functionality).
• Stickers now run on Cobblemon's snowstorm particle engine, allowing for much more dynamic particle effects.
• Stickers can now also play sounds when the Pokemon is sent out.
• Revamped all existing stickers, with some getting complete reworks.

Collect stickers with the new Sticker Book

• The sticker book is a new item which can store stickers, all the way up to the integer limit!
• Hovering over the sticker book will preview the first three rows of stickers inside the book.

Extra features

• Implemented a new sticker/explosion data registry to dynamically add stickers to the Creative Tab (and XEI tabs).
• Added a way to extract stickers and firework stars from a ball capsule by putting the ball capsule and paper in a crafting grid.
• Added a recipe to convert the old stickers to the new stickers. The old sticker ids will be removed in a future update.
