Title: Detect MCCs from the same country as equal

Create a hashmap from each of a country's other MCCs back to a "base" MCC
(chosen arbitrarily) so that they all show as equal. For MCCs that are already
the same, skip the mapping to maintain performance. (The only change for MCCs
that are the same should be provisioning the map in the first place.)
