Fix the Renpho Air Purifier AQI sensor, since AQI is deprecated.

[ThomasADavis]

This fixes the deprecated AQI sensor setting in the Renpho Air Purifier, changing it from AQI to enum with a string mapping.

I've tested this against my purifiers, and it works.

[make-all]

Where are you seeing that aqi device class is deprecated? It is not mentioned in the documentation, and there is no blog post about it.

HA Also complains about it, and this fixes it.

``` is what this fixes.

[ThomasADavis]

From the sensor classes, AQI according to the docs has no units defined..

SensorDeviceClass.AQI	None	Air Quality Index

but it wants an int/float, not a string.

[make-all]

I see they have added a list of non-numeric device classes, and aqi is not among them. I guess it does make sense, since the I in AQI stands for index, so it should really be numeric, even though many devices have something labelled AQI which is a good/fair/poor categorisation like this.
