PM10 error for zhimi.airp.vb4
Just updated to latest version, with new device, zhimi.airp.vb4.  thanks for adding.

It comes with the following error, 

[2/2/2022, 12:19:26 PM] [miot] [Polly] [Miot Device] Connected to device: zhimi.airp.vb4
[2/2/2022, 12:19:26 PM] [miot] [Polly] Setup failed!
[2/2/2022, 12:19:26 PM] [miot] [Polly] TypeError: this.getDevice(...).getPM10Density is not a function

it seems then as a result I am not getting any of the sensor values for temp, humidity, pm2.5 or pm10.
