[Feature]: Support externally controlled dehumidifiers

[jharrell75]

What problem are you trying to solve?

I have a E100W in the attic that I am moving to external control using my main thermostat dehumidify relay since it doesn't get an accurate RH internally.

This integration seems to work pretty well for internally controlled dehumidifiers but specifically throws a repair error if it's externally controlled. Is there any specific reason to exclude them? As far as I can tell they are still reporting their sensors and the on/off control is still active, only the humidity setting itself has no effect.

The April air app still allows on/off control but seems to purposely hide the diagnostic sensors in external control, which is annoying but I think thats just a UI decision on their part.

Proposed change

Allow integration to work with externally controlled dehumidifiers allowing on/off control and sensor readings.

Additional context

The line that control this is here, not sure if more needs to be done than just removing the check:

ha-aprilaire-cloud/custom_components/aprilaire_cloud/profiles.py

Lines 237 to 238 in 6165ed6

	if dehumidifier_setup.get("controlType") != SUPPORTED_CONTROL_TYPE:
	return "unsupported_control_type"

I have confirmed that by commenting out the above line the integration seems to work fine with the externally controlled dehumidifier reporting all diagnostics sensors correctly.

I may work on a more complete pull request, not sure if something can be done to show the device is externally controlled and the humidity set points are not functional.

One other note the humidifier card in HA on shows the unit as off or on even when internally controlled but the docs show that it can display "humidifying" and "drying" and "idle" based on action, looks like this integration is returning action correct in the code so not sure if the issue is with the card or with the action not actually working correctly.

So the action of "drying" was not working during to this line which doesn't include "active" status:

ha-aprilaire-cloud/custom_components/aprilaire_cloud/humidifier.py
