 * Give `methods/fadvi` a `gpu` label. Without one it was scheduled on the CPU partition with no GPU attached, so it
     trained on the CPU and hit its walltime on every dataset.
 * Give `methods/scalex` a `midcpu` label instead of `lowcpu`. It is CPU-bound only because its engine has no CUDA.

 * Split Scanorama into two methods/scores
-    - Split Scanorama into embedding (integrate) and count-correction (correct) modes, instead of running both together. 
-        This makes clear what the reported score(s) are describing, and also corrects the misleadingly low score that 
-        the combined method receives. The scores for each component  are in line with their scores from v1, where the modes 
-        were separated.
