 * Refactored to improve code quality and to optimize SequenceReservoirSampler, SequencePoolSampler, SequenceInsertionSampler, SequenceCompositeSampler.
 * Minor optimizations to Permutation.scramble() methods.

 ### Removed
 * Removed the previously deprecated (in v5.1.0) constructor `org.cicirello.sequences.distance.EditDistance(double, double, double)`. To compute edit distance with double-valued costs for arrays and other sequences, use the existing `EditDistanceDouble` class instead. This does not impact the class with the same name that computes edit distance for permutations (i.e., the `org.cicirello.permutations.distance.EditDistance` class still accepts doubles for the costs).
 * Removed default method implementations in SequenceSampler interface (all interface methods now implemented in the implementing classes).

 * Integrated Find Security Bugs static analysis into build process.
 * Discontinued publication of a `jar-with-dependencies` (BREAKING CHANGE only if you were using the fat jar).
