cytof_addToFCS: Add data to the original FCS files
In raman91/cytofkit2: cytofkit: an integrated mass cytometry data analysis pipeline

Store the new dimension transformed data and cluster data into the exprs matrix in new fcs files under analyzedFCSdir

cytof_addToFCS(data, rawFCSdir, origSampNames = NULL, analyzedFCSdir,
  transformed_cols = c("tsne_1", "tsne_2"),
  cluster_cols = c("cluster"), clusterIDs = NULL,
  specifySampleNames = NULL, inLgclTrans = TRUE)

`data`	The new data matrix to be added in.
`rawFCSdir`	The directory containing the original fcs files.
`origSampNames`	Vector of original names of samples, if samples were renamed.
`analyzedFCSdir`	The directory to store the new fcs files.
`transformed_cols`	The column name of the dimension transformed data in `data`.
`cluster_cols`	The column name of the cluster data in `data`.
`clusterIDs`	Table of cell cluster IDs for each clustering method
`specifySampleNames`	Used only if sample names differ from those in raw fcs.
`inLgclTrans`	If `TRUE`, apply the inverse lgcl transformation to the the cluster data before saving
