Do we need `cluster_sce()`?

[jashapiro]

I just noted that there is already a function scran::clusterCells() which does almost everything we do with cluster_sce(), with the exception being saving the results back to a separate SCE object.

Since we can add the cluster info with a line like:

sce$clusters <- scran::clusterCells(
  sce, 
  use.dimred = "PCA", 
  BLUSPARAM=NNGraphParam(k=15)
)

are we sure we need our own version of the function?

hmm probably not... do we want to take this out before we release?

This function is only used in internal functions within the package and we don't use it in other places like scpca-downstream-analyses. Because of that, we will just remove it from being exported right now and go ahead and release. Later we can actually remove the function and switch to using scran::clusterCells().
