Espeasy MH-Z19

[MH-Z19] Allow for B-version and add filtering by TD-er ...

The "B" version of the sensor does not output an S value, but does internally apply a dynamic response filter on the samples based on the amount of fluctiation in the data. The implemented filter does something similar for the "A" version and for both adds the option for an extra delay filter to smooth the data. Default filter setting ("off") is the old behavior, where only stable values are ...
