Update nitrokey crate to 0.4.0-alpha.0

This is patch marks the first step in the process of updating the
nitrokey dependency to version 0.4. In particular, it integrates with
the first alpha version.
The main change on the nitrocli side accompanying the version bump is
that the nitrokey::CommandError got replaced by a more general
nitrokey::Error which includes the former variant.
