The following APDU sequence reads the first 256 bytes of the data group 1 as specified in ICAO LDS

(logical data structure) for machine readable travel documents with open access. It first selects the

issuer application using its AID (0xA0 0x00 0x00 0x02 0x47 0x10 0x01), then selects the DG1 file

(0x01 0x01) and then does a read binary.
