Fix rmr_rpobe command line bug; add test coverage

This change corrects a deficency in the command line parsing of
the rmr_probe support utility. It also adds unit test code to
cover a significant portion of the SI95 code which was previously
not covered.  Commented out code in SI95 was also removed to
reduce the sonar grumblings.
