Describe the feature

As the construction is completely in json, it would be very helpful to be able to datagen a book instead of writing it by hand and having to worry about formatting and json errors.

Additional context

An alternative solution would be a generator like the one at https://misode.github.io/worldgen/biome/ but this isn't as useful since it doesn't update automatically.

It's worth noting there's a 1.18.2 mod for this:
https://github.com/KhanhPham05/PatchouliDataGen
I could attempt to port it and perhaps PR it when possible (though I'm not the most experienced modder so I'm not the best person to do so). Let me know if you'd prefer that or if you plan to do this yourself as I'd be happy to help.

Never mind, the lib was ported today. I'd still prefer and included system, but it works for now.
