dieOutcomesfunction

One die of a kind worked through its own rules, before any keeping or dropping: the chance of each amount it adds to the total, from least up. For dice that are added, that is what the die is worth, explosions and all; for dice that are counted, it is the successes it makes less the ones it takes away. Exact as the rules are played: rerolls stop after MAX_REROLLS and explosions after MAX_EXPLOSIONS, here as in a roll.
