How to use the rpcq.messages function in rpcq

In particular, for Clifford C, and Pauli P, this returns the PauliTerm
        representing CPC^{\dagger}.

        :param Program clifford: A Program that consists only of Clifford operations.
        :param PauliTerm pauli_in: A PauliTerm to be acted on by clifford via conjugation.
