Clustering option for heatmap

[abenjak]

Hello,

Thanks for the great tool!

A clustered heatmap can be very useful for detecting problematic samples in a cohort.
This is easily implemented by adding order='hclust', hclust.method='ward.D2' to the corrplot function in BAMixChecker.py:813.

It would be great to have an option, say -c --cluster to let the user decide whether a clustered heatmap should be produced.

Thanks,
Andrej
