refactor:extract ThresholdUtils remove featureEnvy

[lokeshwartabjula]

Extract Class:

Package Location: package fiji.plugin.trackmate.util;

Description: The class, TMUtils was identified with Insufficient Modularization, hence few methods were extracted or removed from TMUtils and then created a new class with the name ThresholdUtils as it had a group of methods that help to calculate threshold values. Methods that were extracted are getPercentile, getRange, getNBins, histogram, otsuThreshold, otsuThresholdIndex. Note that after extraction, Insufficient Modularization smell was eradicated.
