pySim-shell: add command to manually query the Card Key Provider

Browse Source 
The Card Key Provider is a built in mechanism of pySim-shell which
allows the user to read key material from a CSV file in order to
avoid having to lookup and enter the key material himself. The
lookup normally done by the pySim-shell commands automatically.

However, in some cases it may also be useful to be able to query the
CSV file manually in order to get certain fields displayed. Such a
command is in particular helpful to check and diagnose the CSV data
source.
