Crying Obsidian Portals for Fast Travel

Introduce a mechanic where Crying Obsidian can be used to build a new type of portal. Unlike standard portals, these do not follow the 8-block Overworld-to-Nether coordinate ratio. Stepping through opens a completely random location in the target dimension (and vice versa). Once the player goes through, the exit portal is generated, and both portals become permanently linked based on their respective chunks. Breaking one portal does not break or remove the other one. It helps players quickly access distant, unplundered regions or rare biomes **An option can desable this for multiplayer.
