sensors: add support for BME688 sensor
Add support for BME688 sensor based on BME680 implementation. The BME688 is nearly identical to the BME680, and this implementation reuses much of the existing BME680 code. However, there are some differences related to gas measurements that make it impractical to use the same driver without significantly complicating it. BME688 also supports parallel mode which isn't yet supported. Signed-off-by: raiden00pl <raiden00@railab.me>
