When dealing with embedded devices, storage is more often than not some kind of flash device, on which the memory is usually counted as powers of 1024 instead of powers of 1000. As such, people may prefer reports using IEC prefixes [0] instead of the SI prefixes. Add an option to that effect. We use argparse's ability to use custom actions [1] [2], to provide a set of options that act on a boolean, but has a single help entry and internally ensures consistency of the settings. We could have been using the more conventional store_true/store_false actions instead, but that would have meant either two help entries, one for each set of options, and/or some logic after parse_args() to check the validity of the settings.
