Add ozip decryption for Oppo/Realme device

This function will automatically decrypt .ozip file in a .zip and it will
save the .zip in the same folder of the .ozip and with the same name.
After the decryption, the flash will start.

To enable this function you have to set a Boardconfig flag with the
decryption key like i did here:
