This PR is to add data chunking and compression features. By using additional metadata and manipulate the space between data object file offsets, these features can be developed without breaking the NetCDF file format specifications.
More information about the design and implementation are described in K. Hou, Q. Kang, S. Lee, A. Agrawal, A. Choudhary, W. Liao. Supporting Data Compression in PnetCDF, published in the International Conference on Big Data, 2021.
An example program is available in ./examples/C/chunk_compress.c
