Generate a heatmap for consensus peaks

[ftabaro]

Description of feature

Hello,

I would like to propose a module to plot consensus peak set. I find myself generating DeepTools heatmaps of the consensus peak set from nf-core/cutandrun to desire such feature to be brought in.

I envision the output of this feature as an extra folder in the reporting folder. This output may be also included in the MultiQC report.
