Todo:

Engines I consider to implement:

• stf which just applies a scalar factor: stfinv::STFEngineIdentity
• stf read from file (always the same stf, independent of data and synthetics): stfinv::STFEngineFixedWavelet
• stf which normalizes the synthetics in the Fourier domain; this ensures that data and synthetic always contain the same signal energy; this avoid a zero stf during the first iterations starting from a new inappropriate initial model: stfinv::STFEngineNormalize
• causal and time limited stf as found by convolution condition in the time domain; this is a solution to a system of linear equations and will requires LAPACK: stfinv::STFEngineFiniteCausal
