-New method:
 public synchronized byte[] APDUPlainTransceive(byte[] c_apdu) throws DlReaderException, InterruptedException
 Function that send c_apdu bytes to the to the ISO14443-4A tag supporting APDU protocol and, after successfully executed APDU command by the tag selected returns R-APDU. Count of the R-APDU bytes varies depending on the issued APDU command. Minimum number of the R-APDU bytes is 2 and in that case contains SW1 and SW2.

Added new method:
public synchronized void blockWrite(byte[] data, byte block_address, byte auth_mode, byte[] key) throws DlReaderException, InterruptedException
Write data (16 bytes) in to the blocks designated by the block_address parameter.
On the Mifare Classic compatible cards You have to skip direct write in to sector trailers. Otherwise You get an exception with code = 10 (FORBIDEN_DIRECT_WRITE_IN_SECTOR_TRAILER = 0x0A).
