Redeem Vault

When users want to exit their TECH Vault position, they may redeem their TVLT tokens at will. The TECH Vault will return to users their pro-rata share of TECH and USDC in the vault, according to the current proportions of those assets held. The Vault will liquidate its TECH/USDC LP positions as needed, converting them to TECH and USDC, before returning these assets to the redeeming user.
