LazyFutureStream operations on underlying futures
Some LazyFutureSteam operations operate on the underlying futures rather than their results (e.g. limit and skip) but most operate on the result of an operation rather than the underlying Stream of CompletableFutures. Events are triggered when a result completes. In some cases it may be more efficient or useful to perform Stream operations on the underlying Futures. These methods typically end with ****Futures suffix.
