事件解析漏了indexed 字段

事件的indexed字段未解析，只解析了非indexed字段

如果要解析indexed字段，需要从Log的topics字段取数据：
- topics[0]代表事件topic本身
- topics[1]对应第一个indexed字段，topics[2]对应第二个indexed字段，以此类推

非indexed字段从Log的data字段解析即可

Start by locating the event and log parsing entry point in the Java SDK and tracing how topics and data are currently handled. Verify behavior with an event containing indexed and non-indexed fields; done means indexed values from topics after topics[0] and non-indexed values from data are both represented.
