pySim-shell: Make 'apdu' command use logical (and secure) channel 

The 'apdu' command so far bypassed the logical channel and also
the recently-introduced support for secure channels.  Let's change
that, at least by default.  If somebody wants a raw APDU without
secure / logical channel processing, they may use the --raw option.
