[Nambers]

暂时还没测试，因为我跑 MockMemberTest 的时候报错如下:

	Caused by: java.lang.IllegalStateException: Failed to load services for MessageProtocol from your classpath. Check you ClassLoader environment and ensure services for 'net.mamoe.mirai.internal.message.protocol.MessageProtocol' can be loaded. This should not happen if you are using mirai under default JVM classloader or using Mirai Console.If so, please file an issue. If you are trying to load mirai manually from other classloader, e.g. in another plugin system like Minecraft, it's your responsibility to ensure the Java SPI works.
