hsize_t iterateChunks(int  ndims,  bool  delegate(ChunkInfo,  hsize_t)  dg,
                           hid_t fspaceId =  H5S_ALL)

Iterates over all chunks in the dataset, calling a delegate for each.

`ndims`	Number of dimensions in the dataset
`dg`	Delegate to call for each chunk, receives ChunkInfo and index. Return false from delegate to stop iteration early.
`fspaceId`	File dataspace identifier, or H5S_ALL for all chunks

The number of chunks iterated over

HDF5Exception if iteration fails
