Compute Umap coordinates for each event

1	compute_umap(processed_fcs_obj, channels = c("all", "with_desc")[1], k = 30)

`processed_fcs_obj`	list containing a datraframe of processed intensities for each event and informations of channel used
`channels`	vector containing channels to select. Can be "all" to select all channels, "with_desc" to select channels with a marker description or a vector a channels.
`k`	numeric indicating the number of neighbor for phenograph and umap computation
