Deployment of the sixth BalancerRelayer using BatchRelayerLibrary, for combining multiple operations (swaps, joins, etc.) in a single transaction.
This version supports Recovery Mode exits, and adds a new vaultActionsQueryMulticall. This takes the same data as the standard multicall, but does query swaps, joins, and exits instead of the standard state-changing operations. Consequently, this can be called without any approvals.
This version also adds gauge checkpoint / mint capabilities for gauges (both mainnet liquidity gauges and L2 child chain gauges).
