Please expose API to get the maximum number of clusters in dendrogram in heat map.
AKA, the maximum value that can be assigned to heatmap.RowDendrogram.PruningLevel.
The use case is that we are trying to use a silder (placed in text area) to control the position of the pink line in the dendrogram. We need to know this maximum value in order to set the range on this silder.
