Add getOfflinePlayerIfCached(UUID)

[OoLunar]

Is your feature request related to a problem?

#4687 allows us to easily search the usercache.json file, however there's no UUID overload for the method even though the usercache.json file saves the player's UUID.

Describe the solution you'd like.

Adding an getOfflinePlayerIfCached(UUID) overload for the getOfflinePlayerIfCached(String) method.

Describe alternatives you've considered.

Calling getOfflinePlayer(UUID), however that has the possibility of making an HTTP request. As this method will be called upon extensively - though results could be cached - this isn't ideal.

Made a pr, don't know why it wouldn't be merged. Seems like a good idea.

Server#getOfflinePlayer(UUID) does not make any HTTP requests like getOfflinePlayer(String) does, it will get or create an OfflinePlayer instance that might or might not be backed by an existing player.dat file for that UUID, for which you can check with OfflinePlayer#hasPlayedBefore().

@OoLunar as emily said, we'd love to hear your usecase for this.
Cluttering API without a proper usecase is generally not in our interest, so it'd be great if you can give us a proper example :)
Otherwise I'll just close this issue as, yea, the uuid getters do not require a network request.
