• ID_cmd: Command identifier sent by the client, as defined by the std::to_string of the following enum:

  enum CmdID {
      CMD_ID_NOT_FOUND = -1,
      CMD_ID_ID = 0,
      CMD_MAP_ID = 1,
      CMD_PSEUDO_ID = 2,
      CMD_MOVE_ID = 3,
      CMD_CLIENTS_NB_ID = 4,
      CMD_CLIENTS_STATS_ID = 5,
