`xcompat.materials.clay_brick` only exists in Hades.

[Yukitty]

Every game that supports materials includes Clay Lump and Brick Block.

For some reason, only Hades Revisited includes the definition for the clay "ingot" clay_brick directly underneath it, before the water bucket.

[Yukitty]

On closer inspection, it appears that xcompat.materials.brick is also inconsistent on whether it should represent a full node (Minetest Game, Hades Revisited), or an individual brick (Mineclonia, presumably Farlands Reloaded)

So uh, I may have had it backwards, and clay_brick wasn't intended to exist?
But no, brick is in the "nodes section" alongside dirt, grass, and chests... guh...

Requesting clarification.
