Update nitrokey crate to 0.4.0-alpha.2

This change updates the dependency to nitrokey to version 0.4.0-alpha.2.
In addition to minor interface changes for the get_*_firmware_version
and get_*_retry_count functions, several functions that change the
device state now require a mutable handle to the nitrokey. Hence, this
patch a number of function signatures to accept mutable device objects.
