Binance introduced TradeFi futures contracts (e.g., XAUUSDT, XAGUSDT) with a new contractType value "TRADIFI_PERPETUAL". These contracts were not being recognized, causing UnsupportedSymbol errors when subscribing to symbols like XAG-USDT-PERP.

This change adds TRADIFI_PERPETUAL to the list of recognized perpetual contract types in the symbol parsing logic.
