scatter3d now performs axis transformation on error bars

[antoinerg]

Fixes #2962

Applies axis transformation on error bars in scatter3d to deal with log scale appropriately.

I tried to reuse code from scattergl but it turns out it bails out of drawing error bars with negative lower bounds (see #3009)

Not the most ideal fix, but good enough considering the current state of 3D.

Reusing more things for cartesian is probably going to be difficult before we tackle #2646, which we may not tackle before the regl rewrite (#949), so let's get this fix in ASAP 💃

Ok sounds good! I'll merge it now :)
