pySim-shell: add new commandline option "--pure"
by default pySim-shell does all kinds of probing and file selection on startup. This is to determine the card type and to find a suitable card profile. However, in case the card is non yet provisioned this probing may cause a error messages and even might upset the cards internal state. So let's have a commandline option thrugh which we can instruct pySim-shell to skip any initialization and to give us a prompt immediately, so that we can enter custom APDUs
