Monitor UCD90160 for faults at runtime

Add the RuntimeMonitor class that will monitor the
UCD90160 faults in 2 ways:

1) Watch for the PowerLost signal, meaning system
   PGOOD was lost.  When it occurs, analyze the
   chip for errors and then issue a proper shutdown
   so a faulted device doesn't keep getting power.

2) Poll on an interval for nonfatal errors that need
   to be logged but don't cause a PGOOD loss.

The main executable can now launch either the PGOODMonitor
or the RuntimeMonitor based on commandline arguments.
