fd34f22: add a new encoder option and deprecate the old serializer option

how to migrate:
```
// before
const options = {
    channel,
    serializer: {
        serialization(data) { return ... },
        deserialization(data) { return ... },
    },
}

// after
const options = {
    channel,
    encoder: {
        encode(data) { return ... },
        decode(data) { return ... },
    },
}
```
```
// before
const options = {
  channel,
  serializer: NoSerialization,
};

// after
const options = {
  channel,
};
```
```
// before
const options = {
  channel,
  serializer: JSONSerialization(),
};

// after
const options = {
  channel,
  encoder: JSONEncoder(),
};
```
fd34f22: hint added to the CallbackBasedChannel.setup(jsonRPCHandlerCallback) and EventBasedChannel.on(listener).

For an isomorphic instance of AsyncCall (used as both a server and a client), when a new message comes, it does not clear if to call decodeRequest or decodeRespones.

This version introduces a new option encoder to replace serialization. serialization is always working in isomorphic way.
- If hint is "request", (encoder as ServerEncoding).decodeRequest will be called first, if this method does not exist, (encoder as IsomorphicEncoder).decode will be called.
- If hint is "response", (encoder as ClientEncoding).decodeResponse will be called first, if this method does not exist, (encoder as IsomorphicEncoder).decode will be called.
- If hint is not present, only encoder.decode will be called.
