Subject: [PATCH] CMD_READER_HITAG requires always a hitag_data struct

used as SendCommandMIX(CMD_READER_HITAG, RHT2F_UID_ONLY, 0, 0, NULL, 0);
sent to ReaderHitag((hitag_function)packet->oldarg[0], (hitag_data *)packet->data.asBytes);
void ReaderHitag(hitag_function htf, hitag_data *htd)
=> we should always send a hitag_data struct
