TransactionImpl.readUnread()

   Is this still valid? I was looking at `Map<RowColumn, Bytes> 
get(Collection<RowColumn> rowColumns)` and `get(Collection<Bytes> rows, 
Set<Column> columns)` as options but they don't have the `Consumer<Entry<Key, 
Value>> locksSeen` parameter.
   
   Another option would be something like the following, which just runs all 
the `getImpl` call concurrently. It's a little messy but I'd think of someway 
to clean it up.
   ```
   List<CompletableFuture> reads = columnsToRead.entrySet()
               .stream()
               .map(entry -> 
CompletableFuture.runAsync(()->getImpl(entry.getKey(), entry.getValue(), 
locksSeen)))
               .collect(Collectors.toList());
       return CompletableFuture.allOf(reads.toArray(new 
CompletableFuture[]{})).get();
   ```
