language setting info packet

[Stachelbeere1248]

Hypixel has localizations, typically set via /lang.

However, Hypixel-specific mods handle these localizations poorly, and in many cases not at all.
While the primary reason for most modders is probably effort, personally I think just figuring out the correct language should be made easier - randomly guessing regular expressions until one matches is obviously not the way to go, but there aren't that many uniquely localized literals per game, in fact I don't think they even exist for all localized games.

The packet could be event-based on language change with an initial dispatch sometime soon after handshake (probably the most reliable way), or request-based, requiring intercepting later changes downstream (not ideal as the player can change the language in several ways).

If someone knows a good alternative way to detect the language feel free to enlighten me instead.
