test correctness of permutations when getting syndrome measurements

[Krastanov]

Now that we have #4, we can start adding some "property checking" tests. Something along the lines of:

circuit = ... # the straightforward circuit
qubit_permutations = ... # the permutations you are imposing
optimized_permuted_circuit = ... # the circuit with permuted gates

noise_on_all_qubits = ... # a circuit that runs noise on all qubits

pauli_frame_1 = ... # A sufficiently big pauli frame
pftrajectory!(pauli_frame_1, noise_on_all_qubits) # Make the pauli frame noisy

pauli_frame_2 = copy(pauli_frame_1)

# use qubit_permutations to permute the columns of the pauli_frame_2 tableaux

pftrajectory!(pauli_frame_1, circuit)
pftrajectory!(pauli_frame_2, optimized_permuted_circuit)

@test measurement results are the same for the two simulations
