CRC16 caclulator

ISO 14443 refers to CRC_A and CRC_B described in in ISO 13239.
The initial register value shall be 0x6363 or 0xC6C6 in reversed bit order.
Polynomial is 0x1021 and no final XOR is done.
CRC result value should be reflected to least significant bit (LSB) and little-endian byte order.
