improve key handling for CAK7 and overcrypt keys

[WXbet]

better version with the correct length for then keys

• CAK7 and ins7e keys are set to 0x01 on the last byte (length not nessesary)
• Overcrypt keys are set to the required length on the last byte

#include <stdio.h>
#include <stdint.h>
#include <string.h>
int main() {                  // if by chance unfinished...
static uint8_t key[112 + 1] = {0x01,0x02,0x03};
printf("key: ");
for(int32_t i = 0; i < sizeof(key) ; i++) { printf("%02X", key[i]); }
printf(" \nstrlen: %ld sizeof: %ld \n", strlen((char*)key), sizeof(key));

//if (strlen((char*)key) && key[112])
if (strlen((char*)key))
    printf("key is valid!!!\n");
else
    printf("key is invalid!!!\n");
}

out: key: 0102030000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 strlen: 3 sizeof: 113 key is valid!!!
