Kurt ccf87242c1 Eliminate boxing on encounter search (criteria)
struct implementing interface is boxed when passed to method that accepts interface (not generic method).
Removes IDexLevel (no other inheritors but EvoCriteria) and uses the primitive the data is stored (array, not IReadOnlyList) for slightly better perf.
