Print the number of failures (if any)

The star-phor output file contains only the average and standard
deviation for each estimated observable, which is not enough information
for users who want to perform further statistical analyses with their
results. The missing piece of information is the effective number of
realizations. Up to this point, this could not be determined, since
realizations may fail silently.

This commit addresses this issue by printing the number of failed
samples (if greater than zero) at the end of the realization loop as a
warning.
