Internal calibration for humidity, other parameters

[Minhwan]

Hello Mayor, 

Firstly, if you are using BSEC 1.4.8.0, it's the humidity data you got is already calibrated. 

You can check calc_humidity function in bme680.c  and it is used in BSEC. 

And I saw your result and it's within our spec. 

The accuracy tolerance is +-3% r.H.

Thanks,
