Run only for known packages

Although the logic is not well encoded in the file (see #7), it looks like the intention was that, if not all the packages found in the file are in the API bank, don't do anything:

SnifferDog/lib_ver_producer.py

Lines 184 to 185 in 2a855ec

	else:
	print("Might contain some packages that are not included in our API Bank database! It would be great if you can report this to us!")

If would be nice if the program still ran even with a subset of the modules.

Thanks for the suggestion! Will push a fix in the coming weeks. I will leave this just open.
