Description: Tools for exploratory statistical analysis of quantum-hardware
    calibration time series. The package provides simulators for random
    telegraph noise (RTN), power-law noise, and Ornstein-Uhlenbeck dephasing;
    Welch and sine-multitaper power spectral density estimators; a lightweight
    two-state hidden Markov model for switching signals; cumulative sum
    (CUSUM) and binary-segmentation diagnostics for calibration drift;
    residual-quantile interval forecasts; and filter-function calculations for
    illustrative coherence curves. The package includes a reproducible
    generator of simulated superconducting-qubit calibration records; it does
    not retrieve authenticated live provider data. Methodological background
    is provided by Welch (1967) <doi:10.1109/TAU.1967.1161901>, Thomson (1982)
