Implement all commands of Ctap2 (#154)

* WIP: Add part MakeCredentials

* Add test for (and do some fixes) for MakeCredential CTAP1 mapping

* Adjust tests with RelyingParty and name-field

* Fix serialization of MakeCredentialOptions (individually serialize members)

* Temporarily parse credential_public_key just as a byte-vector, until COSE-crate is added and able to actually parse it

* Add Option Unparsed to AttestationStatement, to currently skip parsing it (which would need a DER-parser)

* Add commands GetAssertion and GetAssertionNext. Still missing tests.

* WIP: Add clientpin command with all the crypto functionality commented out

* Remove duplicate Pin-definition

* MakeCredentials and GetAssertion now do not store Pin but PinAuth, which has to be calculated before hand

* MakeCredentials: Remove pointless alias for HIDError

* GetInfo: Fix wrong parsing of response. Forgot to strip away the status-byte

* Make naming of CommandError variants consistent and remove redundant 'Parsing'-variant

* Replace custom error with invalid_length (even though the usage is a bit weird)

* Use From<CommandError>-trait of HIDError to avoid verbose map_err-calls, by using the shorter .into()
