Making Spheres Locatable (Starry Skies 3.x)

There are various vanilla mechanics for locating structures, like Eyes of Ender, Treasure Maps and more.

In dimensions using a Starry Skies chunk generator, mechanics that locate structure are rerouted to locate spheres instead. For this there has to exist a sphere tag that matches the name of the given structure tag.

Example:

An item that locates a structure in the tag worldgen/structure/eye_of_ender_located will instead lead to the next location of the closest sphere in the tag starry_skies/configured_sphere/eye_of_ender_located.
