Standard and CZ interleaved 2Q RB

[paulQM]

Written by Omrie for IQCC.

This uses qiskit to generate the random sequences of Cliffords and transpile the circuits to a basis compatible with our native gates.

The CZ fidelity is calculated from the decay rates of the standard 2Q RB and the CZ interleaved RB and is stored in the state under the macro fidelity field

Pull Request Overview

This PR implements standard and CZ-interleaved two-qubit randomized benchmarking (RB) for quantum computing calibration. The implementation uses Qiskit to generate random Clifford sequences and transpiles circuits to native gate bases, enabling direct measurement of CZ gate fidelity through comparison of decay rates between standard and interleaved RB experiments.

Key changes:

• Added three new calibration nodes for 2Q standard RB, CZ interleaved RB, and a legacy version
• Implemented core RB utilities including circuit generation, transpilation, and fidelity analysis
• Created supporting utilities for QUA program generation, circuit processing, and data analysis
