Initializing states from numpy array

Feature details

I would like initialize a state using the syntax mm.State.from_fock(modes=[0], array=numpy_array) where numpy_array is a 1-dimensional numpy array. This should return a pure state with the values in numpy_array as Fock-basis coefficients.
Right now, an error is thrown if I try this. Also, the example code in the doc string throws an error, "'Coherent' object has no attribute 'ansatz'" array = Coherent(modes, x=0.1).to_fock().ansatz.array

I believe that this can also be done

Hi Jacob. Are you using lab? If so you should switch to lab_dev. Try Ket.from_fock
