neorpc: adjust SignerWithWitness scopes parsing

Browse source 
Ensure that Scopes can be properly parsed not only from the string
representation, but also from a single byte. transaction.Signer
is not affected (checked against the C# implementation), only
RPC-related signer scopes are allowed to be unmarshalled from byte.

Close #3059.
