[Feature Request] Return more structured error for submit_and_wait_bcs when transaction failed.

🚀 Feature Request

Return a more structured error for submit_and_wait_bcs instead of Unknown(anyhow::Error) when transaction failed.

Motivation

Currently submit_and_wait_bcs will return Unknown(anyhow::Error) when transaction failed, which I can only use Regexp to match the string part to identify the actually error.

match result {
  Ok(tx_data) => {}
  Err(RestError::Unknown(e)) if e.to_string().contains(INSUFFICIENT_BALANCE) => {}
  Err(RestError::Unknown(e)) if e.to_string().contains(TOO_MANY_STEPS) => {}

Pitch

I hope the error can hold something like ExecutionStatus

   match resp.info.status() {
            ExecutionStatus::Success => {}
            ExecutionStatus::OutOfGas => {}
            ExecutionStatus::MoveAbort { code, info, .. } => match info {
            }
            _ => {}
   }
}
