Issue description

In the current network, if the protocol between the client and server is inconsistent, the client will be directly kicked, is not conducive to use.
If we add ClientPingPacket, we can declare the client mod version in it, allowing the server to selectively send/not send packet, thereby achieving gentler and more reliable functionality.
If you don't have time, I can create a PR to increase this support, but I need to see your attitude before working on it

That sounds good. You can PR it. I think you will need to store if a player is supported on the server side

Also it would be nice if it can notify the player of the mod version on the server
