We'd better get the option here, and pass that flag to getFileName method

if (index < 0) {
return qualifiedFieldName;
}
return qualifiedFieldName.substring(index + 1);

This will create a new string everytime for deserialization, which is very slow. A better method is rename fieldInfo#qualifiedFieldName into fieldInfo#fieldName, and build it as qualified based on the option.

And we should skip duplicated field name in super class if this option is enabled

@shuyufang Seems we can refactor ClassDef#FieldInfo#qualifiedFieldName into fieldName, and only add classname when parent class has duplicate field with subclass. In this way, we can skip add a new option. Would you like to refactor along this way?
