Above Averaging Algorithm Rework and Crash Fix

[nbollis]

Crash was caused by MS1 and MS2 scans being out of order. The previous algorithm mistakenly added duplicates of the same MS2 scan, leading to a crash on writing the mzML file as the scan numbers were not unique.

This PR changes how averaging DDA scans works by first removing the overlap parameter. The algorithm will iterate through all MS1 scans, adding the number to be averaged to a local collection. The collection will be averaged, the first scan removed, and the next scan inserted before restarting the loop. All unaveraged scans (leading or lagging MS1s or all MSn+) will then be added at the end.

Due to this change in the algorithm, the tests had to be reconsidered.
Test now ensure that the same number of MS1 and MS2 scans are present in the averaged spectrum, that they are in the same order, and that their retention times are correct after averaging.

Converting the averaged MzSpectrum into a MsDataScan was excised to a helper method to clean up the algorithmic methods.

This PR was packed and added to MetaMorpheus. The accompanying MetaMorpheus PR is #2318 and will need to be slightly amended once this version of Mzlib is released
