Subject: Added CLI options, Apache commons-cli lib, anomalous curve key export
  - Added CLI options, see SimpleAPDU.jar -h  - Added Apache commons-cli for
 CLI options, it uses Apache license  - Added support for anomalous curve
 export both reader/applet side:    `java -jar SimpleAPDU.jar -g 10 -b 256 -fp
 -s`    generates 10 curves over ECSP256 an anomalous 256bit curve.
