On Open() detect the board model and configure how physical PINs are mapped to GPIO pin numbers [1]. Model detection is based on content of /sys/firmware/devicetree/base/model [2] . If you are running a weird or very old system which does not have the file, GetBoardPin() won't work.

The behavior of the test is not changed, now it hides BCM bin number and used physical PIN number.
