 - Fixed a bug in the conanfile where the ``stderr`` output from a ``subprocess.Popen`` call was being interpreted as an
   error. Rather, the process return code (0 for success, and anything else for failure) indicates the success.
 - The ``MAX_N_CSS_MEAS`` define is increased to 32 matching the maximum number of coarse sun sensors.
