Complete the function OR $3$ that implements the $3-$qubit to $1-$qubit $OR$ operator. This operator acts on $4$ qubits in the state $|q_0,q_1,q_2,q_3$: and maps it to

or $q_1$ or $\{$:$q_2)$:$.$

The function has

Inputs: None

Returns: A QuantumCircuit object with $4$ qubits and $1$ classical bit that implements the $OR$ operator as described above.

Don't add any measurements to the returned circuit.
