1.11.31 - Pack format 12 and config option for hash in url
Added pack format 12 for 1.19.3 (Please note that at the moment 1.19.3 clients do not work when using the plugin with BungeeCord!)
Added a new config option append-hash-to-url which is enabled by default to work around MC-164316 by appending the hash to the end of pack URLs automatically. Without this the client might not re-download a pack that was changed but with the same URL.
