Transpose array-like in herm_conj
If onsite/hopping value was supplied to the builder as array-like instead of proper array, Hamiltonian could be generated silently without any Hermitian conjugation, if required.
This MR fixes the problem, trying to cast the value to the proper array, if it can't be conjugated and is not a number.
Fixes #406 (closed)
