[SAK-FEA-2] Add dakuten and handakuten

[anafro]

Issue information

• Sakurator last version when issue was suggested: 1.0.0.2
• Type: feature (important)

Why this feature should be added?

Despite the fact that dakuten and handakuten are easy to understand if you know how the letter without them sounds like, but it is still important to add them to the sets of cards.

Difficulty for me

It will be a bit hard to recalculate the petal count for each card set and the point count needed for a game to complete.

Probable issues

So, no, I cannot predict any issue yet that can come with this feature.
