Ensure all methods working on peaksData use the chunk-wise processing

[jorainer]

Chunk-wise processing (#304 ) on peaks data is built-in .peaksapply and should be enabled/used in a consistent way. While all methods do already use the same approach two don't:

• containsMz
• containsNeutralLoss

These should be refactored to use the same call as in ionCount or isCentroided.
