Caelum Mundus core customization

Mostly adds the floating dimensions for the modpack "Caelum Mundus" and some other changes.

Changes:
Vanilla: Adds a few dimensions, and a method to travel dimensions by reaching the top or bottom of the current dimension (Per example, jumping while above the building limit or surrounding yourself with the dimension's bedrock).

Twilight Forest: Adds a dimension.

Infinite Abyss: Dimensions are "stacked" (Just like the other ones)

Alex's Caves: "Adds an "easter egg" above The End"

Crystalcraft Unlimited Java/Spelunkery: Reworks how to obtain the gems (Only "prism" is found in the overworld, you bring the prism into a grindstone/diamond grindstone and "crack it" for a handfull of gems, Prism Set recipes are removed.)

Spelunking Master: Fixed grinding recipes.


Note: This is just a datapack disguised as a mod. There's no code from the mods I've modified
(Besides explicit permission; Apothicon's noise settings in the "skylands" worldgen, as their mesospheric worldgen is what I based of off my own modded dimensions.) Regardless, contact me if there's a problem with the license.
Note2: Thanks MCreator for just creating an empty project so I can add the datapack to it. I had unkown problems with gradle
