Title: Change in peaks() return value. Instead of a zipped tuple of the m/z and intensity values, it returns an m/z list and an intensity list. Enhances performance. 

Changed peaks to return the m/z and intensity list seperatly instead of returning them as zipped tuples. For a function where I had to call spec.peaks 32000 times got the runtime down roughly from 90000 to 300 seconds.

Changed centroidedPeaks to return the m/z and intensity list seperatly so that the return value is consistent with the changed peaks() return value.

Changed _centroid_peaks to return the m/z and intensity list seperatly so that the return value is consistent with the changed peaks() return value.
