Quick Mode: Instead of trying to re-allocate all target genes that were allocated into the noise cluster, only a certain (random) percentage of these target genes is attempted to be re-allocated.
quick_mode = TRUE has to be supplied as an argument to scregclust to
activate this feature (off by default) and the percentage of
noise target genes to re-allocate is given by quick_mode_percent,
a number in [0, 1).
