~trexio_to_orbital_list_up_dn~ function does the same but for both up- and down-spin components
of the determinant and returns two list of orbitals each corresponding to a different component.
~trexio_to_bitfield_list~ function converts the list of occupied orbitals (up- or down-spin)
into the corresponding ~int64_t~ bitfield representation of the determinant.
