Gachapon (WIP)

On-chain automated raffling system.

• Owner is able to create a new raffle by inserting ERC721's into the Gachapon
• Users are able to mint tickets as ERC721's by burning an underlying ERC20
• Owner reveals raffle by requesting Chainlink VRF
• Winning tickets are able to claim the prizes

This repo will move completely to foundry once forge verify-contracts works.
