[Feature Request] Deterministic ordering/sort for child advancements

[son0fether]

Would it be possible to make the child advancements of a parent get listed in some order? Any deterministic order would be fine, such as alphabetical by name, by containing folder, anything. (Probably with a config, off by default, like this mod does for the advancement tabs.)

Motivation: I'm making a modpack where I want a bit of a relationship between advancements (playing bingo), and having some kind of control over ordering would be great.

I know that this is kind of a niche request, and might be impossible in the 1.13+ world. I can see that the load() call where all the better_display, pos_x, pos_y configs were loaded was removed in the move to 1.13, so I know there's probably a reason a feature like this isn't implemented right now, but I wanted to ask. 45d3b4a#diff-b2d45d34c3fa7a709c3df8bac7847bc8553fffb726726723ef4b92a182304a9fL30

Thanks for making this mod.
