Include ERC-20 asset address in cancel and withdraw events

[PaulRBerg]

The lack of the ERC-20 asset in these events makes it impossible to build certain data queries on Dune, e.g. "what is the volume of stablecoin withdrawals".

v2-core/src/interfaces/ISablierV2Lockup.sol

Lines 29 to 35 in 8ca98d3

	event CancelLockupStream(
	uint256 indexed streamId,
	address indexed sender,
	address indexed recipient,
	uint128 senderAmount,
	uint128 recipientAmount
	);

v2-core/src/interfaces/ISablierV2Lockup.sol

Line 53 in 8ca98d3

event WithdrawFromLockupStream(uint256 indexed streamId, address indexed to, uint128 amount);

Let's do it, there would only be a slight increase in the gas cost, which is totally fine.
