Create new Segmented UBI functionality for whitelisted wallets

[decentralauren]

Business Description

In addition to 1. Direct Payments triggered by NFT and 2. Segmented UBI based on demographic info, we want to add a third contract type that allows a group administrator to add and manage a list of wallet addresses to a pool.

Questions & To-Dos

• Should we create a simple interface for this in the dapp? Is the explorer easy enough to navigate by someone like Chris for them to use this?
• Create GoodCollective pool UI to display this type of pool. Should show wallet address of person who has admin access. Should also show a state for the Admin in which there is an "edit" button to adjust the wallet list.
