Construct ChunkedFillArray with chunks from other DiskArray #36
Description
We should be able to construct a ChunkedFillArray with the chunks from another DiskArray to ensure they have the same chunking structure.
Currently ChunkedFillArray takes a NTuple of ints to indicate the chunk sizes. Maybe this should save the Chunks directly and only have a convenience function to construct the chunks from a NTuple.
I will prepare a PR.
