We have smartcontract.ParameterPair structure that can be properly
marshalled and passed to RPC server as an element of smartcontract.Map
structure. However, RPC server can't unmarshal map values properly
without this change.
This change is compatible with C# node.

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.
