Implement the pin command and rename clear to pin clear

We have functionality for changing the Nitrokey's user & admin PINs as
well as for resetting the user PIN coming up. With the prospect of this
new functionality arriving, it makes sense to introduce a new top-level
command for the sole purpose of PIN management.
This change introduces such a command, pin, and moves the existing clear
command for clearing the PIN cache into it.
