Add support for Galcon GL8000B

Hi,

Can you please add support for Galcon GL8000B model ?

Tried using the GL9001A type, but it is not working.

In my opinion, devices of 9000 series are not very suitable for continuous monitoring. The connection is broken after about 20 seconds of inactivity. So it has to be polled every 10 seconds. To work in this mode, you have to use a separate power source. It seems that there are some versions of Galcon that do not connect to the R4S gateway on ESP32 at all for some unknown to me reasons. You can save the gateway log when trying to connect to the device, having previously set the "UART debug" option in the settings. If ESP connects to Galcon, then there are differences in the protocol versions 8000 and 9000. Then you will have to save the log of the device's operation with the native Android application.
