Info.query_order_by_oid returns unknownOid sometimes

[satwikkansal]

I fetch orders through Info.open_orders, and then loop over those orders to call info.query_order_by_oid (using the same orderID as received from the response of info.open_orders I receive the following response

{
  "status": "unknownOid"
}

Sample orderIDs

265211960704
265131800711
266053654384
266059605108
265288767983

I've created pull request #268 to address this issue. The fix adds the missing dex parameter to query_order_by_oid and query_order_by_cloid methods, ensuring consistency with other order-related methods in the SDK. Please review when you have time.
