Test Array storing different compressors, endian and attributes (#405)

* Test correct handling of endian data

Try storing data as both big endian and little endian. Ensure that the
data stored remains equal regardless of the stored endian order.

* Test store's handling of Array attributes

Make sure that the JSON contains the keys added to the Array attributes.

* Add test of multiple compressors with Arrays
