Computing shanten is expensive, and counting yaku somewhat as well.

• External service through websocket or REST API ?
• Algorithm could be implemented in flux or protograph, but costly and lots of effort

Inspiration: https://github.com/MahjongRepository/mahjong/blob/master/mahjong/shanten.py
Need to adapt it so that when the hand is tenpai, we also return the isolated tiles to discard with a 3n+2 hand, and the winning tiles with a 3n+1 hand (isolated + pairs if there are 2 pairs + both sides of tatsu first + middle of tatsu second)
Once that is done, we can run https://github.com/MahjongRepository/mahjong/blob/master/mahjong/hand_calculating/hand.py for each possible winning tile to check for invalid hands eg no yaku.
