Workspace Method sensor_responseFrequencySwitching

Description

Simulation of "frequency switching".

A general method for frequency switching. The WSM
sensor_responseBackendFrequencySwitching gives a description of
this observation technique, and is also a more straightforward
 method for pure singel sideband cases.

It is here assume that sensor_responseMultiMixerBackend has been
used to calculate the spectrum for two LO positions. This method
calculates the difference between these two spectra, where the
second spectrum gets weight 1 and the first weight -1 (as in
sensor_responseBackendFrequencySwitching).

Output frequency grids are taken from the second spectrum.
