This PR adds a set of calibration protocols for fixed-frequency Cross-Resonance (CR) gates under
calibrations/CrossResonance_calibrations_fixed_frequency.The scripts implement CR Rabi experiments with QST, followed by systematic Hamiltonian tomography for cr drive/cancellation drive optimizations.Associated
