CCID: Check if reader restarts WWT upon NULL procedure byte
The reader will receive a NULL procedure byte every 0.2 for a long time.
The reader may only respond with a status that time extension was
requested. At the end the SIM proceeds with a valid response. This
response must be returned by the reader.
