This datapack removes the large caves that were added in 1.18
Since removing the new caves greatly lowers the amount of caves in general, the amount of old caves has also been increased.
Aquifers have also been turned off, since they don't really generate well in the old caves. Water-filled caves still exist below oceans, rivers and lakes, since afaik there is no easy way to remove them.
Note that mojang changed the way the old caves generate in 1.18, so caves aren't exactly as they were in 1.17 and before.
