Wrong Shanten Calculating

[taeho-gwon]

sh = Shanten()
tiles = TilesConverter.string_to_34_array(man='123456789', honors='1111')
print(sh.calculate_shanten_for_regular_hand(tiles))
tiles2 = TilesConverter.string_to_34_array(man='123456789', pin='1111')
print(sh.calculate_shanten_for_regular_hand(tiles2))

output

In shanten calculation, 4 non-honor tiles can be used as meld and waiting itself as pair, but it is impossible.

Thanks for the report, the shanten calculations are more correct with 14 tiles.

With 13 tiles, it may have the issue as you mentioned.

The bug needed to be fixed.
