New crate air_interpreter_sede introduces a flexible serialization and deserialization infrastructure. Low level API: the Format trait and related. It includes simple and universal mechanisms for serializing any possible (e.g. implementing the Serde traits) value. High level API: Representation trait and related. It allows declaring representation types that can serialize and deserialize only certain types (for example, InterpreterDataRepr can serialize only the InterpreterData, but deserialize InterpreterData and Versions` types), producing newtype values as serialization results. The serialized representation of CallResults now contains byte arrays, not strings, because the new infrastructure serializes to byte arrays only. Also, the basic support for multicodecs is added.
