[World Generator] Ocean Only World / Water World

• Remade from scratch
• More simple, cleaner method: Raise the water level in the world instead of telling the world to generate only water biomes (which became very tedious to do so with 1.18 and pointless for you cannot tell biome-locked structures to generate in a different biome)
• Jungle and Desert pyramids still won't generate. I don't know why.
• Aside that according to my best knowledge everything else is working and is present (villages, mansions, outposts, witch huts, igloos, ancient cities, lush and dripstone caves, strongholds, random nether portals)
• Every biome is present aside from vegetation (obviously) 
• In \data\minecraft\worldgen\noise_settings\overworld.json (within the data pack itself) you can edit the water level if you find it too much. All you have to do is to change "sea_level": 185 to your preferred level like "sea_level": 120. However, there are some very tall natural stuff like icebergs and mountains which will make dry land so the ocean only thing will be kind of spoiled though. You can only change the water level before using the data pack and generating the world
• Since the dimension itself isn't modified, only the noise settings now each and every time a different seed generates so thousands of people won't be using the same seed. Hallelujah. 
• Safe spawning is a risk and a wager for you may spawn deep under the sea, within the cave system, or even inside stone or if you're lucky you'll spawn on an ice field with lots of "dry" land. If you're even more lucky you'll spawn in a village. That's the best. See for yourself with trial and error.
• Now every village and every house with chest have a chance to have water breathing potion for it became common to use them in such a water world. If you want to go and explore the depths your best bet is to gather as much water breathing potion as you can and go for an adventure.
• Fisher's huts now have a chance to have: respiration 1-3, depth strider 1-3 and aqua affinity 1 enchanted books and even turtle helmets. They're quite rare though.

Enjoy? I guess?
