(De)Serialize message containing oneof field between protobufjs

[Joel-PeakMetrics]

Hello,

First off, thank you for all of the work on this library. I really appreciate the ability to use typescript with protobufs (and I'm using Deno which all seems to work well).

I have a message type that has a oneof field. When serializing that message type to wire-format, I'm leveraging the Confluent Schema Registry's protobuf solution, which is using this https://www.npmjs.com/package/protobufjs. The problem is the way protobufjs converts a message's oneof field to wire-format and back again doesn't seem to work with the protobuf-ts method.

Message:

message Test {
    message InnerMessageA {
       string id = 1;
    }
    message InnerMessageB {
       uint32 id = 1;
    }
    oneof inner_field {
        InnerMessageA inner_message_a = 1;
        InnerMessageB inner_message_b = 2;
    }
}

// using protobuf-ts
const example = Test.create({
  innerField: {
    oneofKind: "innerMessageA",
    innerMessageA: {}
});

// using protobufjs
const example = Test.create({
  innerMessageA: {}
});

I've worked around the encoding problem by converting the protobuf-ts to JSON, then providing to protobufjs. However, how can I convert from protobufjs to protobuf-ts? Should I also use a JSON intermediate step?

TYIA for your help, please let me know if you need any additional info here.
