There was a discussion about the '--raw-binary' option to deprecate it because
'--output-format=binary' or '-o binary' will make a same result.

You can find the discussion on the Github PR #342 in following link:
????https://github.com/linux-nvme/nvme-cli/pull/342

For the newly added subcommand, it doesn't need to support the '--raw-binary'
option anymore.

Thanks,
