Simplify ThreatByKing to be a single Score. In the current master, ThreatByKing is an array of two Scores, one for when we have a single attack and one for when we have many. The latter case is very rarely called during bench and was recently given a strange negative value during a tuning run, as pointed out by @candirufish on commit efd4ca2. Here, we simplify away this second case entirely, and increase the remaining ThreatByKing to compensate. Although I derived the parameter tweak independently, with the goal of preserving the same average bonus, I later noticed that a very similar Score had already been derived by an ongoing SPSA tuning session. I therefore recognize @candirufish for first discovering these values. I would also like to thank @Rocky640 for valuable feedback that pointed me in the direction of ThreatByKing.
