Some private methods (relating to calibration/compensation) are no longer exposed. In addition, the driver auto-detects the chip (BMP280 or BME280) and acts accordingly, rather than requiring the specification of a chip id in the ctor. The getHumidity() method no longer accepts an arguement representing pressure at sea level. A new method is provided to specify this. Signed-off-by: Jon Trulson <jtrulson@ics.com>
