* Add basic setup for multi-PIN
- Reserve the storage keys for maximum of 8 user slots.
- Modify the storage functions to take a slot_id parameter.
- Add the slot_count() customization.
- Assume slot_id as a parameter when needed except these places:
- Entrance functions of command processing that directly takes the
command parameter structure. slot_id is set as 0, and will be
parsed from the parameters when we enable the feature.
- MakeCredential/GetAssertion/AuthenticatorConfig will take the
slot_id from active token state when we enable the feature,
resulting in an `Option<usize>`. Below code will act on the option
value correctly. When the feature isn't enabled, we're always
referring to the only PIN slot so set slot_id as Some(0).
- GetInfo returns verdict of whether PIN is supported and enabled, and
whether PIN needs to be forced changed. There will be new fields to
represent those values when the feature is enabled, and the old
fields will not be populated. So when the feature isn't enabled, we
can treat slot_id as 0.
Not covered in this commit:
- Unittests for other slots. The existing tests all pass and I plan to
add unittests for multi-slot case after the codebase allows enabling
the feature.
- Persisting and checking the slot_id in credentials. This is planned to
come in the next commit.

* Add crate arbitrary as ctap's optional dependency, when feature "fuzz"
is activated.
* Derive Arbitrary for all the necessary types in order to generate the
concrete types from random bytes.
* Add a fuzz target that transforms the input to valid format for
MakeCredential.
