Added exception for label atom count

The testing of potential overlap can lead to physically impossible label states (more nitrogen are in the label than in the molecule) and the error "too many atoms in label" is called. This is not necessary, as the test of this overlap is not possible or necessary and stops the program to work with certain labels. Introducing an exception for it allows the program to continue running.
