pySim-shell: re-organize Card Key Provider related options

As we plan to support other formats as data source for the
Card Key Provider soon, the more commandline options may be added
and it makes sense to group the Card Key Provider options in a
dedicated group.

Let's also rename the option "--csv-column-key" to just "--column-key".
The column encryption is a generic concept and not CSV format specific.
(let's silently keep the "--csv-column-key" argument so maintain backward
compatibility)
