eosc get account shows memory (and probably others) in KB instead of KiB

The `eosc get account` shows RAM quota/usage:

```
quota:           1.951  MB   used:           882.2  KB
```

But it should be 

```
quota:           1.951  MiB   used:           882.2  KiB
```

Indeed, the account for which is was taken has `903367` bytes used, for which `882.2` comes from `903367 / 1024 = 882.2` so the numeric value is in `KiB` and not in `KB`.
