Returns the number of times each asset index won across the workflow's rapids.

The entries of winCounter are ordered by compared side: the first is the first compared side, the second is the second, and so on. That order is the order of the workflow's compare blueprint, which is also the order the sides' assets appear in on every rapid returned by /workflow/simple/{workflowId}/results — so rendering the entries as they arrive lines up with the individual rapids. Sides that have not won a rapid yet are present with a count of 0.
