Probably the air purifier sends a 1 for aqi when the measurement failed.
With change from this PR, library returns None as aqi value in such situation.

Fixes: #925

Could you add a comment for which model this fix is required? At the moment the miot class provides the support for these models:

    "zhimi-airpurifier-mb3": AirPurifierMiot,  # mb3 (3/3H)
    "zhimi-airpurifier-ma4": AirPurifierMiot,  # ma4 (3)

It seems that the side effect of this fix is that there is no AQI in case the airpurifier just returns AQI=1, not as an error but as a measured value.

I just re-confirmed manually - turning on the device, it shows 1 on the screen.
When I imitated some pollution in the air it started returning correct value.

So, it seems AQI=1 => error does not always seems to be true.
Looking at #925 it seems those incorrect 1 values are peaks. Maybe it would be better to ignore a single "1" value but if they are coming again and again treat them as correct / measured values ?
