HDF5 High-Level Direct Chunk Operations Binding

This module provides D bindings for HDF5 Direct Chunk Operations (H5DO API). The Direct Chunk Operations API provides functions for reading and writing raw data chunks directly, bypassing the HDF5 filter pipeline. This enables high-performance I/O for applications that handle compression externally.
