Huge performance enhancement of our TimsTOF raw data reader

The TimsTOF raw data reader inside i2MassChroQ is now fully paralelized and uses an agressive cache system. On the same computer, previous version did the conversion of one Hela sample (120 minutes) in 1h10 and the current version now does it in 21 minutes using 4 threads. The same sample converted by ProteoWizard using 4 threads last 35 minutes. Identification results given by i2MassChroQ are better than same samples converted by ProteoWizard.
