MulticallV3

Multicall aggregates results from multiple contract constant function calls.

This reduces the number of separate JSON RPC requests that need to be sent, which is especially useful if using remote nodes like Infura. This guarantees that all values returned are from the same block (like an atomic read) and returning the block number the values are from (giving them important context so that results from old blocks can be ignored if they're from an out-of-date node).
