Add support for the GET_STATUS command

This patch adds support for the GET_STATUS command that returns the
status information common to all Nitrokey devices.  It can be accessed
using the Device::get_status function and is stored in a Status struct.

Due to a bug in the Storage firmware [0], the GET_STATUS command returns
wrong firmware versions and serial numbers.  Until this is fixed in
libnitrokey [1], we have to manually execute the GET_DEVICE_STATUS
command to fix these values for the Nitrokey Storage.

Also, this leads to a name clash with the existing Storage::get_status
function, which will be renamed in an upcoming patch.
