According to the NERSC HPSS documentation (https://docs.nersc.gov/filesystems/archive/#avoid-very-large-files), files over 2TB are inefficient when put to HPSS. They recommend breaking files up into 500GB chunks if they get over that limit.

The hsi handler mcscript.task.archive_handler_hsi() should:

Inspect the size of an archive file to put.
Put the file directly using hsi if smaller than threshold, or
use split to break up the file into smaller segments and put those with hsi.

mcscript should also provide a wrapper function to fetch and reassemble archives,
