This should work like the RiskScorer for Adyen, taking an API response, consulting a lookup table, and giving a numerical score for AVS and CVV results.
This will be used in the pending transaction resolver created in T291223 so that we don't have to rely on DonationInterface's AVS/CVV scores.
As preparation for deployment, copy (and reformat) the current Ingenico risk scores from the payments LocalSettings file to the private ingenico/main.yaml SmashPig settings file.
