BME680 ambient temperature compensation

[MassaRoddel]

The driver uses bme680_dev::amb_temp and BSEC  BSEC_INPUT_HEATSOURCE. Do both have to be set for corrent compensation?

Example: amb_temp = 22C and BSEC_INPUT_HEATSOURCE 5C because the PCB is 5C warmer

If you know clearly about the temperature offset coming from PCB self heating,  then you can set this temperature offset as heat source as input when calling the lib to process the data.    Then you just need to use temperature value read from sensor and heat source ( 2 input of lib).  no need to set amb temperature into bsec lib.
