Requetes serveur --> client:
- version incompatible : (fait/à tester)
    b'E\x00C{"translate":"multiplayer.disconnect.incompatible","with":["1.16.5"]}' (message tiré d'un srv 1.19)
- Info pour la liste des serveurs (exemple) : 
    b'\xca\x01\x00\xc7\x01{"previewsChat":false,"description":{"text":"\xc2\xa79Aujourd\u0027hui : serveur ouvert de\xc2\xa72 truc\xc2\xa79 jusqu\u0027\xc3\xa0\xc2\xa74 truc\xc2\xa79."},"players":{"max":10,"online":0},"version":{"name":"1.19","protocol":759}}'
    #####
    TRES IMPORTANT
    #####
        - les § sont codés \xc2\xa7 dans les requetes. Cela donne \xc2\xa7 + code couleur
            --> \xc2\xa79 par exemple pour §9 ou \u00A79

J'ai retirer le load de plugin api parce-que ca buggait !

Offline mode
If the server is in offline mode, it will not send the Encryption Request packet, and likewise, the client should not send Encryption Response. In this case, encryption is never enabled, and no authentication is performed.

Clients can tell that a server is in offline mode if the server sends a Login Success without sending Encryption Request.
