Reverse proxy to multiple minecraft servers based on domain

This project already does proxying
internet:25565 -> lazymc:25565 -> minecraft server:25566

It is possible to determine the domain the user is connecting to from the login packet
Based on this fact it is possible to direct them to different minecraft servers as such

server-a.example.com:25565 \                  / minecraft server-a:25566
                           +-> lazymc:25565 ->+
server-b.example.com:25565 /                  \ minecraft server-b:25567

An example of this is infrared (https://github.com/haveachin/infrared)

I would imagine it could work by splitting lazymc.toml to multiple files in a config directory:

# file 1
[public]
address="server-a.example.com"
[server]
address="127.0.0.1:22566"

# file 2
[public]
address="server-b.example.com"
[server]
address="127.0.0.1:22567"
```</div>

I've added a draft PR #42 for this, if you have some time it'd be great if you could tell me if I'm going the right direction

If you use docker, I have created a solution to this problem: https://github.com/joesturge/lazymc-docker-proxy?tab=readme-ov-file#multiple-server-support
