An incredibly simple plugin for Velocity that receives and responds to the worldinfo:world_id (and legacy world_id) packet used by multiple client-sided mods to differentiate between different server worlds.

The primary difference between this plugin and others I have found is that this primarily supports world id during the Configuration phase of connecting to a server.
In fact, the entire reason for this project's existence is I needed to identify a server during that Configuration phase and couldn't find any other plugins that did it at the time.

A plugin config is intended eventually, but is not included currently.
