tsqn 1.1.0 (2026-03-16)

Performance

• Optimized corQn() and covQn() to reduce temporary allocations and redundant computations.
• Reworked corMatQn() and covMatQn() to cache per-column Qn scales and compute symmetric matrix entries once.
• Optimized robacf() internals to avoid repeated scale recomputation in multivariate settings.
• Reduced loop overhead in PerioMrob(), PerQn(), and GPH_estimate() while preserving formulas and returned values.
