New End Biome: Obsidian Spikes

The spikes are similar to those from the ice spike biome from the overworld, but boosted in size, converted into obsidian, and stuck on the standard end highlands, with the ground gaining some obsidian patches as well. Digging into the spikes and pillars reveals bits of crying obsidian within, not exposed to air. Some spikes are slanted, for variety.

Chorus fruit is, logically, less common around here, and where is has grown, it is creeping to the sides of the spikes, curling as it rises, almost like a natural spiral staircase.

Occasionally, the player might find an obsidian spike (specifically the structure from the dragon isle), with an end crystal atop it. That way, if the player is bored, they can blow it up.

The end is such a flat place, a biome with serious verticality to break up the monotony would be advantageous, I think. Plus, it begs the player to test out their elytra flight skills to land on a spike.
