WithdrawalSenderTag.from

Derives the sender tag that identifies the indexed parent-chain WithdrawalProcessed event for a Zone withdrawal.

The transactionHash is the Zone transaction containing the ZoneOutbox.requestWithdrawal call. The protocol defines a user withdrawal sender tag as keccak256(abi.encodePacked(sender, transactionHash, fallbackNonce)). Internal deposit bounce-backs use the canonical zero-sender tag derived from address(0) and bytes32(0) without a fallback nonce.
