[建议]增加对卡片消息的过滤选项

[CDN18]

ChatLearning会记录群聊内的几乎所有消息，包括分享类的卡片消息，例如：

[{'type': 'App', 'content': '{"config":{"forward":true,"type":"card","autosize":true},"prompt":"[应用]地图","from":1,"app":"com.tencent.map","ver":"1.1.2.4","view":"LocationShare","meta":{"Location.Search":{"from":"plusPanel","id":"1**********5","lat":"**.*****5","lng":"***.******","name":"****","address":"**省**市**区**路**号"}},"desc":""}'}]

是否可以实现一个过滤规则，过滤这种消息呢？
