Some fixes for interactive management

[msirringhaus]

1. Fix typo
2. Allow deserializing PublicKeyCredentialDescriptor from JSON and CBOR, instead of only CBOR.
3. Automatically clear cached PUAT and try getting a new one (e.g.: when doing a few BioEnrollment-operations and then do CredentialManagement-operations).

Why would that happen? We should be storing permissions with the cached PinUvAuthToken and checking them prior to sending any commands. I suppose we might still need this code to handle PUATs that have expired, so maybe only the example in the comment needs to be changed.

[msirringhaus]

I actually used it as the comment described. But we should indeed check the permissions before using it.

On a general note: I wanted to have this caching-mechanism as lenient as possible, to never cause non-recoverable errors. If the cached PUAT is bad for whatever reason, auth-rs should just skip it and try again to get a new one.
Hence the change in handle_errors!(). And yes, we also need this for expired ones. But also for "bad" ones, since they are externally provided (all zeros for example, or just a random byte-array).

Looks good, just make the one change I mention below.

[jschanck]

We want to check membership rather than equality. Looks like the version of bitflags that we're using has a contains function.

(aside: I'm a little concerned that more recent versions of bitflags are quite different. Long term we should remove that dependency. It's not really doing much for us.)

[msirringhaus]

Ok, done.
We also need to think about adding a rust-toolchain.toml-file to the repo, to avoid clippy randomly breaking the CI.
From what I can tell, this time it was a clippy-bug and not a real problem.

Thanks!
