Converts iy to y assuming a fixed frequency resolution.

This is a short-cut, avoiding yCalc(), that can be used to convert monochromatic pencil beam data to spectra with a fixed resolution.

The method mimics a spectrometer with rectangular response functions, all having the same width (df). The position of the first spectrometer channel is set to f_grid[0] + df / 2. The centre frequency of channels are returned as y_f.

Auxiliary variables and jacobian s are not handled.
