Getcontractopcodes

Re-executes a transaction and returns a result containing detailed information for the execution, including all values from the {@code stack}, {@code memory} and {@code storage} and the entire trace of opcodes that were executed during the replay. Note that to provide the output, the transaction needs to be re-executed on the EVM, which may take a significant amount of time to complete if stack and memory information is requested.
