Now uppercase letters imply Si units, so use lowercase everywhere. We could stay with uppercase, but then we'd have to deal with rounding, etc. Also, some output / error messages change slightly (instead of "GB" we're now saying "GiB"). One test enhancement might be to add some new tests for the units changes but for now let's just get the test back to passing.
