Extension of HclustParam with hclust function choice

[BananaCancer]

The HclustParam is currently using stats::hclust as clustering function. But other functions exist to do hierarchical clustering, for example fastcluster::hclust.
In some situations, the choice of the function used would be handy as the computation time can be quite high.

A solution would be to add a parameter to HclustParam to let the user choose the function. The default still being stats::hclust.

The new use would be: clusterRows(sce, HclustParam(clust.func = fastcluster::hclust))

Do you think such addition to bluster would be ok?

Seems reasonable to me.
