/**
 * Constructs Write Buffer APDU.  This APDU is usually sent right after
 * the Create_Object_APDU is sent.  This APDU writes the actual object
 * content into the object that was created with Create_Object_APDU.
 * This APDU is used for both write and re-writes of data.
 * The object data is stored starting from the byte specified by the
 * offset parameter.
 * Up to 240 bytes can be transferred with a single APDU.  If more bytes
 * need to be transferred, then multiple WriteObject commands must be
 * used with different offsets.
 *
 * WriteObject APDU format:
 * CLA    0x84
 * INS    0x54
 * P1     0x00
 * P2     0x00
 * lc     Data Size + 9
 * DATA   <Data Parameters>
 *
 * [DATA] Parameters are:
 *        Long Object ID;
 *        Long Offset
 *        Byte Data Size;
 *        Byte[] Object Data
 *
 * Connection requirement:
 *   Secure Channel
 *
 * Possible error Status Codes:
 *  9C 06 - unauthorized
 *  9C 07 - object not found
 *
 * @param object_id as defined in APDU
 * @param offset
 * @param data
 * @see APDU
