* Parse slot_id in use from token state
Support switching to multi-PIN feature and making the default slots 8.
But the command to switch to multi-PIN isn't exposed yet because the
implementation isn't ready.
Main change of this commit is to cache the slot_id in use inside token
state, and retrieve it from token state when needed.
* Fix once_cell dependency (#548)
* fixed version of once_cell
* fixes comments
* removes unnecessary fuzz dependency
* Fix styles
