```
A StringsSketchAggregator is a BinaryOperator that takes in ItemsSketchs of Strings and merges them together using ItemsSketch.merge(ItemsSketch).
NB: We cannot provide a generic aggregator for any type T as we need to clone the first sketch that is supplied to the _aggregate method and that requires serialising and deserialising which requires a specific serialiser.
