After installing rpg-dice, it should be available from the command line:

pip install rpg-dice
roll 2d6

E.g. "2d20 + 4d6".

Figure out a way to return partial results of a roll, e.g. for a roll "2d6" the result could be 7, with partial results 2 and 5.

Handle strings like "2d8 + 4"

When enabled, the max/min value would be returned. Has to work well with #4 . At the beginning we can assume that a roll with advantage/disadvantage always roll the same dice twice, so only a flag is required. Remember to handle a case when both advantage and disadvantage is selected (either raise an exception or perform a normal roll).

E.g. "2d8 - 2d4". Question: should negative results be allowed?
