In some cases user might already know what chunks need to be scanned to answer a particular query. Using `chunks_in` function we can skip calculating chunks involved in particular query which should result in better performances as well. A simple example: `SELECT * FROM hypertable WHERE chunks_in(hypertable, ARRAY[1,2])`
