Inkbird: Add support for ITH-11-B BLE thermometer hygrometer

I just received my new Inkbird ITH-11-B Thermometer Hygrometer (INKBIRD Bluetooth Indoor Outdoor Hygrometer Thermometer ITH-11-B)

It uses BLE to send information.

Unfortunately, it doesn’t seem to be supported by the Inkbird integration at this moment

I don’t know how can I help to add support for this new device.
