PIV key generation fails

When trying to generate a key for PIV the command fails as follows:

~ nitropy nk3 piv --experimental generate-key
Command line tool to interact with Nitrokey devices 0.8.3
Enter the PIN:
Nitrokey Nitrokey 3
Critical error:

This is actually a documentation issue as the command lacks parameters. However, could you change the error message to something like: Missing arguments: x, y, z or at least show what -h would show?

It's not that the argument are missing, it's that the default values are invalid (in this case the admin key or the PIN). We can indeed improve the error messages in that case.
