Bridgepy

- fix python requires to 3.10 to allow writing union types as X | Y
- add game state diagram to readme

- fix cannot view game when not 4 players yet
- add quick guide

- make `Game` json-serializable back and forth with `jsons`
python
from dataclasses import asdict
import jsons


game: Game = Game(id = GameId("1"), player_ids = [PlayerId("111")])
json_str: str = jsons.dumps(asdict(game))
game: Game = jsons.load(jsons.loads(json_str), Game)

- expose delete game from bridge client
python
def delete_game(self, game_id: GameId) -> None:

- auto deal after the 4th guy join the game
- define code, msg in biz exception for upstream usage
- throw player not found early when try to view game, bid, choose partner, trick
- fix unit test

- deal again if one player's hand less than 4 points

- `bridgepy` is a python package for playing floating bridge!
- first need to create your own `game_datastore: Datastore[GameId, Game]` and override these methods, you can choose your own datastore, e.g. mysql, google sheet
- `insert(game)`
- `update(game)`
- `delete(game_id)`
- `query(game_id)`
- then inject it to `BridgeClient(game_datastore)`, then you are able to use these methods for players (clients) to play bridge game (server) together!
- `create_game(player_id, game_id)`
- `join_game(player_id, game_id)`
- `view_game(player_id, game_id)`
- `bid(player_id, game_id, bid)`
- `choose_partner(player_id, game_id, partner)`
- `trick(player_id, game_id, trick)`
