BulkTransfer

BulkTransfer main use case is for an EOA to save some gas by batching multiple transferFrom calls.

It has 3 functions

function	description	gas comments
bulkTransfer20(address token, Call[] calls)	Transfers ERC20 token to an array of (target, amount) tuples.	Comparing testGasBaseline20 with testGasTransfer20*, it's not worth using for less than 4 transfers
bulkTransfer721(address token, Call[] calls)	Transfer ERC721 token to an array of (target, tokenId) tuples.	Comparing testGasBaseline721 with testGasTransfer721*, it's already slightly worth for 2 transfers (and it gets better)
bulkTransfer721Lite(address token, address to, uint256[] tokenIds)	Transfer an array of tokenIds of ERC721 token to a single address.	Comparing testGasBaseline721 with testGasTransfer721Lite*, it's already quite worth for 2 transfers (and it gets even better)

Do not forget either approve (ERC20/721) or setApprovalForAll (ERC721) need to be used before any of these.
