Numerical convergence testing revealed several serious bugs in TriggerInterpolation.{h,c} as well as a fundamental unsuitability of the Lanczos and real/imaginary part cubic spline interpolation schemes. This code is used by gstlal and affects localization results for offline runs but not online runs; gstlal online runs provide SNR time series to BAYESTAR and so the trigger times are ignored. This is a rewrite to fix those bugs, improve test coverage, eliminate unnecessary heap allocations, and add one more interpolation algorithm. The new CubicSplineAmpPhase algorithm is the recommended one.
