VOC for image with no objects is fatal

[mikefrandsen]

I don't think it should be a requirement that every image has 1 or more labelled objects.

Code works fine (and outputs a 0-length YOLO output) simply by changing Format.py from returning error condition to printing a warning:

                 if len(objects) == 0:
-                    return False, "number object zero"
+                    #return False, "number object zero"
+                    print("WARNING: no objects in file: {}".format(filename))
