+
Freezes the Redis data base of an ArchiveAsync to a data.table::data.table().
+No further points can be added to the archive but the data can be accessed and analyzed.
+Useful when the Redis data base is not permanently available.
+Use the callback bbotk.async_freeze_archive to freeze the archive after the optimization has finished.
