Function qdk_sim::linalg::extend_two_to_n

pub fn extend_two_to_n(
    data: ArrayView2<'_, C64>, 
    idx_qubit1: usize, 
    idx_qubit2: usize, 
    n_qubits: usize
) -> Array2<C64>

Given a view of an array representing a matrix acting on two-qubit states, extends that array to act on $n$ qubits.
