Remarks
For nodes of node type 1 (chunked raw data nodes), the key is formatted as follows:
Bytes 1-4 Size of chunk in bytes. Bytes 4-8: Filter mask, a 32-bit bit field indicating which filters have been skipped For this chunk. Each filter has an index number In the pipeline (starting at 0, With the first filter To apply) And If that filter Is skipped, the bit corresponding To its index Is Set.
(D + 1) 64-bit fields: The offset Of the chunk within the dataset where D Is the number Of dimensions Of the dataset, And the last value Is the offset within the dataset's datatype and should always be zero. For example, if a chunk in a 3-dimensional dataset begins at the position [5,5,5], there will be three such 64-bit values, each with the value of 5, followed by a 0 value.
