Save the full AlertSystem state to disk
SaveAlertSystem.RdThis helper writes the complete seurat_obj@misc[[misc_name]]
list to an RDS file, so that AlertSystem results can be re-attached
later without recomputing. This is equivalent to the RDS file written
by AlertSystemScore(..., out_dir = ...) (the
*_AlertSystem_info.rds file), but can be called manually at
any time.
