Binance Liquidations insert to QUESTDB failed

[OnlyC]

Describe the bug
E i.q.c.l.t.LineTcpConnectionContext [99] could not parse measurement, INVALID_FIELD_VALUE at 100, line (may be mangled due to partial parsing): 'liquidations-BINANCE_FUTURES,symbol=RSR-USDT-PERP side="buy",quantity=50639.0,price=0.005961,id=None'

This is because the Liquidation order of Binance doesn't included an order_id (None).

To Reproduce
Steps to reproduce the behavior:

• Subscribe to liquidations channel of Binance futures
• Save to QuestDB

Expected behavior
Can ignore the field, or can be inserted as null value
