Escape commands for the uTrust 47xx F
With Amendment 1 of the PC/SC specification, Part 3, a method to define vendor specific commands

method. However, most of the escape commands listed here are not defined according to this
method because of backward compatibility reasons.
All newly defined commands will adhere to this new standard. See the command
