Added chat tunnels. chat tunnels allow you to make it so worlds can only see player chat messages from specific worlds. For example, you can have the overworld, the end, and the nether in one chat tunnel. While you have your minigame world in a different tunnel. This will allow you to separate chat messages between worlds.
The relevant config is located in HPWP/chat_tunnels.yml.
You can set the chat tunnel for a world in the world specified config file
chat tunnels are not currently in /pwp gui you can see the reason listed below
Things to be added in future updates:
In order to add chat tunnels to the config GUI I need to wait for a library to be updated to 1.17. So in a future update be on the lookout for chat tunnels to be added to /pwp gui
