Release 2.1.30 (#472)

* [wip] Fix Sodium world loading timeout

* Send more chunks because Sodium likes that

* Remove debug-related stuff

* Fix 0,0 chunk not being sent

* Send all chunks to 1.20.3+

* 9 chunks because Sodium is greedy

 Sonar is unlikely to ever falsely prevent a player from joining the server since Minecraft uses the TCP protocol, which means that packets are always sent in the correct order. Therefore, lag or ping should not affect the bot check.
 If you or one of your players experiences a false positive, make sure to report it by opening a [GitHub issue](https://github.com/jonesdevelopment/sonar/issues/new/choose) or a ticket on the [Discord server](https://jonesdev.xyz/discord/).
