BingX handle_balance() keyError, called in watch_orders()

Description

In bingx.py, handle_balance() has a dictionary keyError. Namely, it calls self.balance[type]['info'] = data, before self.balance has been defined as a dictionary. I suggest adding a line self.balance[type] = {} before making this call. The code below is the unedited version.

I found this error because handle_balance() is called in watch_orders() (watching swaps), and it constantly drew a keyError.

Code

      def handle_balance(self, client: Client, message):
        # spot
        #     {
        #         "e":"ACCOUNT_UPDATE",

        #         "a":{
        #            "B":[

        #                  "bc":"-1.00000000000000000000",
