pySim-shell: make APDU command available on the lowest level
The apdu command is used to communicate with the card on the lowest possible level. Lets make it available even before a card profile (rs) is avalable. This is especially useful when the card has no files on it, in this situation pySim-shell will not be able to assign a profile to the card at all. We can then use the apdu command to equip the card with the most basic files and start over.
