ParseRollString parses a string of roll info into a DiceInfo's fields.

func explodes(d int, m map[int]struct{}) []int { r := Roll(d) rolls := make([]int, 0) rolls = append(rolls, r) if _, ok := m[r]; ok { } return rolls}.

RollExplodes keeps rerolling until not hitting an explode die number.

DiceInfo contains the information about a roll.
