The Refund Module is a smart contract that facilitates the management of refunds concerning the PIKKA SUI memecoin rugpull, including a unique feature to boost refunds under certain conditions. It provides a structured way to fund a refund pool, add addresses eligible for refunds, and claim refunds.

Users who have lost funds in the rugpull event have two refund options:

1. 100% Refund: Users who lost money in the scam can claim a full refund. Only those affected are eligible.
2. 150% Refund: Users claiming their refund through Rinbot receive an additional 50% of the amount lost. Funds will be available for buying and selling NFTs and Tokens on Rinbot.

The workflow works as follows:

1. Aldrin publishes package on-chain, thus initializing the RefundPool and receiving a Publisher object
2. Aldrin and partners fund the pool via permissionless endpoint refund::fund
3. Aldrin adds list of affected addresses and respective amounts lost to the RefundPool.
4. Users can freely claim 100% of their funds back via refund::claim_refund, or
5. Users can use Rinbot to claim 150% of their funds back, via refund::claim_refund_boosted
