How can the master key be updated in the MKSK algorithm?

[Caroline-521]

By default, QPOS is injected TMK in factory. default TMK: 0123456789ABCDEFFEDCBA9876543210.

Server side should use default TMK to encrypt new TMK to get encrypted new TMK key and calculate its Key Check Value, then call API pos.updateMasterKey() to inject into terminal.

String demoNewMasterKey="22222222222222222222222222222222"
String encDemoNewMasterKey = TDES.tdesECBEncrypt(tmk, demoNewMasterKey)); 

//encDemoNewMasterKey = B4ABA2BB791C50E7B4ABA2BB791C50E7
String demoNewMasterKeyKcv = TDES.tdesECBEncrypt(demoNewMasterKey, "0000000000000000")); 

//call api to inject new master key, let keyIndex =0
pos.setMasterKey(encDemoNewMasterKey, demoNewMasterKeyKcv, //new master key
                    keyIndex);
