Fix pyfive branch with latest Pyfive branch h5netdf

[valeriupredoi]

• Integration with Pyfive hash NCAS-CMS/pyfive@82dc2a9
• Functional (tests pass)
• Tested with gold test (3400 chunks, old S3 proxy): yes, ~92s for max 150 threads, identical time with OLD pyfive
• Merging this since timing performance is identical to old Pyfive

Historical info

This is to start using @bnlawrence 's standardized branch https://github.com/NCAS-CMS/pyfive/tree/h5netcdf

Issue below has been solved by @bnlawrence in Pyfive's NCAS-CMS/pyfive@82dc2a9

with

        # retrieve coordinates from chunk index
        storeinfo = ds.get_chunk_info_from_chunk_coord(chunk_coords)
        offset, size = storeinfo.byte_offset, storeinfo.size

ds.get_chunk_info_from_chunk_coord is extremely useful in the general context of a file type

There is already a fairly critical issue:

Issue with indexing

• test used as benchmark: tests/test_byte_order.py::test_byte_order[big]
• old Pyfive from detached head: NCAS-CMS/pyfive@1f61d6c via ENH: Support for dimension labels and scales pyfive#21 (comment) (thank you @bnlawrence for preserving that!!)
• new Pyfive: standard branch https://github.com/NCAS-CMS/pyfive/tree/h5netcdf (no mods)
