TS 102 221 specifies that (in case of a class 4 command) and as SW
62xx or 63xx, we should send a GET RESPONSE just like in the 61xx
case in order to get the respective response.
As we don't really know if it's a case1/2/3/4 command in the
pySim.transport, let's always send the GET RESPONSE in case SW 62xx or
63xx are received. It shouldn't hurt - in the worst case there's no
response available...
