Sebastiaan van Stijn ddbb503dc7 client: change Raw fields to be json.RawMessage
These fields store the raw JSON data that we received, and should
never container bytes that are non-JSON (as we'd error out when
failing to unmarshal).

Change the type to a json.RawMessage, which:

- Is more explicit on intent
- Can still be used as a regular []byte in all cases

And, while it's not expected to be marshaled to JSON, doing so will also
print the output in a readable format instead of base64 encoding;

    package main

    import (
        "encoding/json"
        "fmt"
    )

    func main() {
        foo := struct {
            Bytes []byte
            Raw   json.RawMessage
        }{
            Bytes: []byte(`{"hello": "world"}`),
            Raw:   json.RawMessage(`{"hello": "world"}`),
        }

        out, _ := json.MarshalIndent(foo, "", "  ")
        fmt.Println(string(out))
    }

Will print:

    {
      "Bytes": "eyJoZWxsbyI6ICJ3b3JsZCJ9",
      "Raw": {
        "hello": "world"
      }
    }
