File structure

The file may start with up to 64k "garbage". Then follows a partition pack, given by the following byte sequence:

 byte 0-10     0x06, 0x0E, 0x2B, 0x34, 0x02, 0x05, 0x01, 0x01, 0x0D, 0x01, 0x02 (may not appear in the "garbage")
 byte 11       version (currently 0x01)
 byte 12       structure type (here 0x01 for partition)
 byte 13-15    depends on structure type
