[Feature request] Cache gathered results for use in multiplayer

[ShaneTRS]

Currently going into a server and trying to view generation details will give you no information at all It would be nice to be able to configure a fall-back pool of information, or just use the last generated set of information Configurable caching will also give a performance boost on weaker machines, so that's another reason to consider.

Obviously the previously cached information could be just outright inaccurate in the current world, but this isn't much of an issue if you're playing on 1.18.1 and joining 1.18.1 servers (both using the default datapack).

This is slightly different from #11, but it's the same concept, so I understand if it's something you're not interested in implementing.
