TransactionTraceStatus is the status of the transaction execution and will let you know if the transaction
was successful or not.
A successful transaction has been recorded to the blockchain's state for calls in it that were successful.
This means it's possible only a subset of the calls were properly recorded, refer to [calls[].state_reverted] field
to determine which calls were reverted.
A quirks of the Ethereum protocol is that a transaction FAILED or REVERTED still affects the blockchain's
state for some of the state changes. Indeed, in those cases, the transactions fees are still paid to the miner
which means there is a balance change for the transaction's emitter (e.g. from) to pay the gas fees, an optional
balance change for gas refunded to the transaction's emitter (e.g. from) and a balance change for the miner who
received the transaction fees. There is also a nonce change for the transaction's emitter (e.g. from).
This means that to properly record the state changes for a transaction, you need to conditionally procees the
transaction's status.
For a SUCCEEDED transaction, you iterate over the calls array and record the state changes for each call for
which state_reverted == false (if a transaction succeeded, the call at #0 will always state_reverted == false
because it aligns with the transaction).
For a FAILED or REVERTED transaction, you iterate over the root call (e.g. at #0, will always exist) for
balance changes you process those where reason is either REASON_GAS_BUY, REASON_GAS_REFUND or
REASON_REWARD_TRANSACTION_FEE and for nonce change, still on the root call, you pick the nonce change which the
smallest ordinal (if more than one).
