Add `check_box_size` option for `add` method in `Compound.add()`

[daico007]

PR Summary:

Add verbose option for add method in Compound.add(). When provided a list of compound to Compound, the method would recursively calling itself to add each compound. During this process, there is a final step to check if the new compound bounding box is bigger than the Compound.Box. The time for Compound.get_boundingbox(), however, would really add up in this process (scale up really badly if you get to the >10,000 range). Hence, I am adding an verbose option for this method to be able to turn it off when adding individual particle if a list/iterable is provided.
