Add support for IAQ, eCO2 and bVOCe

[R-K-H]

You can see here that through the C library there are available sensor readings from the device.

Upon reviewing the patch there seems to be sensor data through the use of the API (most likely proprietary calculations) as provided in https://www.bosch-sensortec.com/media/boschsensortec/downloads/bsec/bsec_1-4-8-0_generic_release.zip in the examples/bsec_iot_example.c

I'm not sure if it is able to be supported in this library by extending the function

bme680-python/library/bme680/__init__.py

Thanks!

It looks like you need the C library libalgobsec from their driver to access these values (they are calculated from the sensor readings) therefore I'm closing the issue.
