Same as spectral_propmat_pathFromPath() but with adaptive path.

The path is filled with extra points if a single frequency point has an optical thickness larger than max_tau in a single step. The step size is halved until the optical thickness is below the limit, and additional points are added to the path parameters.

As a bailout, the step size is not allowed to be smaller than max_stepsize, albeit at least 3 points are added if any point is added.
