Improvement Suggestion

EthGetTransactionReceipt currently replays the message, but this isn't strictly necessary:

1. We can get the event's CID from the receipt.
2. We can determine what the "total cost" should have been from the gas used, gas limit, fee cap, premium, etc. I.e., we can just re-run ComputeGasOutputs.
