Truncated jump target address with oso (0x66)

In
```
$ echo "66 70 00" | ./udcli/udcli -o 19730f -x
000000000019730f 667000           o16 jo 0x7312
```
I would expect the target address as 0x197311. See below:

```
$ echo "70 00" | ./udcli/udcli -o 19730f -x
000000000019730f 7000             jo 0x197311
```
