Fahrenheit has some rounding issues

Describe The Bug:

When using Fahrenheit, setting the temperature on an AC doesn't work properly:

60F maps to 60F on the AC.
61F maps to 60F on the AC.
62F maps to 62F on the AC.
63F maps to 62F on the AC.
64F maps to 64F on the AC.
64F maps to 64F on the AC.
etc.

Using Home Assistant to set the temperature to 63.1F, for example, will set the AC to 63F.

To Reproduce:

Add an AC to the plugin.
Set the mode to Fahrenheit.
Set it to various temperatures.
Odd-number temperatures will round down to the previous even number.

Expected behavior:

The temperatures should work properly in Fahrenheit.

It seems like the plugin is converting Fahrenheit to Celsius internally and then back to Fahrenheit when sending to ConnectLife with setCoolingThresholdTemperature().
