Add Teleportation benchmark

Description

Add teleportation benchmark to teleportation.py from tracking issue #691

Follows pattern from seven_qubit_steane_code.py where a private function does a single teleportation on a block of 3 qubits which can then be repeated for multiple blocks.

Fixes #(691)
