Handle multiplication of `ForEachObject` container by numpy array

I think I found a bug in instrument.py. The following code fails to run:

i = lisainstrument.Instrument()
i.simulate()

and gives the following error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

      1 i = lisainstrument.Instrument()
----> 2 i.simulate()

    430         self.keep_all = keep_all

TypeError: unsupported operand type for *: '<class 'lisainstrument.containers.ForEachSC'>' and '<class 'numpy.ndarray'>'

I think the issue is that the for ForEachObject container does not handle multiplication by a numpy array but only by a scalar. This should be a quick fix...
