chrwiseSignatures to analyze signature interactions

The package provides several functions to calculate mutational signature interaction metrics.

• cor_coda - pearson correlations based on compositional data analysis
• cooccurrence - co-occurrence or mutual exclusivity based on Fisher's exact test
• bcmi - Bias-corrected Mutual Information from mpmi package
• cor_sigs - Spearman or Pearson correlations

The package also provides a function to produce summary interaction networks based on calculated interaction metrics.

Check the documentation of function plot_interaction_networks to see how plotting works.
