Feature Request: Replace IR Aircon "Current Temperature" with reading from SwitchBot Thermometer & Hygrometer
### Problem

The temperature in Homekit always reads as "24°c" on all my IR Air Conditioners.  I do have SwitchBot Thermometer & Hygrometers in each room which shows the correct temperature.  It would be nice if there was a configuration option to use the "Current Temperature" reading from another device to replace the static number that the IR device shows.

### Solution

Add a configuration option to replace "Current Temperature" for an IR Aircon with another Switchbot device.  The user would specify the temperature sensor's device name or device id and the plugin would report that device's "Current Temperature" as the IR Aircon's "Current Temperature".

### Alternatives

If the specified device doesn't have a "Current Temperature" or the device becomes unavailable, then it reverts to 24°c.

### Additional context

It would be a nice quality of life thing to have the numbers on the IR Aircon units be accurate instead of a static number that can't change.  I'm not sure what restrictions exist that may prevent it from being possible, but if you can, that would be great!  And if I missed a setting that would let me, then sorry!  I tried to look, but I'm fairly new to homebridge.  Thanks for the plugin!
