-------------
* Fixed bug in ``dms_merge``, where normalization of prefs or diffprefs was not occurring when the user provided two or more identical pref or diffpref files
* Added y-axis label override option in ``plot.PlotDepth()`` and corrected ``dms_summarizealignments`` to label the y-axis as 'number of barcodes' when summarizing barcoded subamplicon data.
* Added ``merge_method`` choice ``rescale`` to ``dms_merge`` to rescale a preferences file by a ``--stringencyparameter``.
