Simple dice roll simulator, translating "human readable" dice definition like "3d6" to set of rolls.
Default roll definition 3d6+1 means:
Roll 3 times, 6 sides dice, add 1 to final sum.
Exploding dice are when rolls the maximum on a die, then can roll that die again and the new die roll result is added to the original.
3d6! means - roll 3 times, 6 sides dice, reroll every "6" adding new result to final sum.
Simple throw.
result := ThrowDices("3d6+1").Sum()
To get more random results, use the Initialize function once (and only once, since Go 1.19), preferably at the beginning of the code.
