data Chunk a Source

The array starts with index 0. We always consider a subarray of body starting at offset with size size. This way we safe copy operations and we can efficiently drop, take and append chunk lists. Unfortunately, Data.Array does not provide subarrays with sharing. Every chunk must have at least size 1.
