AuraBalVault - Compounder

The AuraBalVault compounder is ERC4626 compatible

Stake auraBal into the AuraBalVault, which will automatically compound the rewards. The Vault earns three reward tokens: BAL, bb-a-USD, and AURA. BAL and bb-a-USD are sold in the market for auraBal, which is then re-stake. AURA added as an additional reward token that can be claimed.
