Main Pollutant missing

Appears that AirVisual has changed their API and no longer has main pollutant in their free plan. This is being discussed in this thread.

It appears an update is required to remove this or perhaps switch to another provider. I have noticed a few others that appear to still support this

I am sure there are others as well

I updated the code so that the card doesn't crash when one of the sensors isn't present. Feel free to test and let me know.
