diceR 2.2.0

• New abs argument in consensus_cluster(): control whether to apply absolute value to Spearman and Pearson correlation matrices before subtracting from one (@tiagochst, #161)
• New distance matrix option, distance = "pearson"
• Use blockcluster instead of mixedClust as the latter is now archived
• Update tests in consensus_cluster() that skip when suggested packages are not installed
