Remove the print line from line 603 of holeFilling.cpp

There is a print line in this file which I don't think should be there because it isn't dependent on the 'verbose' flag and prints all the time, which is very annoying.

Plus one to this. I tried redirecting stdout and stderr in a context manager, before realizing it was coming from subprocesses spawned by the underlying library.
