fix: do criterion benchmark comparision the correct way around

The optional criterion benchmark A/B-test had swapped the "A" and "B"
data, causing regressions to show up as improvements and improvements to
show up as regressions.

See also [1] for a documentation of the criterion commandline
arguments.
