… creation

Add a member of type `fido_blob_t` named `type_winhello` to `fido_cred_t`.

Add `fido_cred_set_type_winhello` which takes a pointer to an array of
32 bit signed integers and length. The old `type` member of
`fido_cred_t` is set to the first element of this array of public key
types. It is stored as a `fido_blob_t`.

Create a copy of `decode_attcred` as `decode_attcred_multiple_cose` to
handle using the list of key types.

Create a copy of `cbor_decode_cred_authdata` as `cbor_decode_cred_authdata_multiple_cose` to
handle using the array of key types.
