scaling | The step width can be scaled by this factor. Often it is adventageous to iterate in slightly smaller steps over the spectrum (or chromatogram). |

returns the next sensible m/z (or RT) position for scanning through a spectrum (or chromatogram) (fast access since we can start search from lastPackage)
In the middle of a package, we increase the position by the average spacing of the input data (times a scaling factor). At the end of a package, we jump straight to the beginning of the next package.

scaling of the step width
Each package stores its own step width, which is the average spacing of the input data points. This step width can be adjusted by the scaling factor. Often it is advantageous to use a step width which is somewhat smaller than the average raw data spacing.
