Any plan to support reliable json protocol in C++ for the websocket client?

### Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is.
Example: I am trying to use azure webpubsub in C++, but I can't find webpubsub client C++ SDK.

### Describe the solution you'd like
An alternative SDK to C# one [here](https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/webpubsub/Azure.Messaging.WebPubSub.Client/src/WebPubSubClient.cs), support features:
- Auto reconnect
- Auto retry sending
- Sequence Ack
- Auto rejoin group

Or at least provide a protocol serialization and deserialization SDK which make dev easier

### Additional context

Start by reviewing the linked C# WebPubSubClient.cs implementation and compare its auto-reconnect, retry, sequence-acknowledgement, and group-rejoin behavior with the requested C++ websocket client scope. Before implementation, clarify whether the goal is a complete client SDK or only JSON protocol serialization and deserialization; done should be defined by the selected scope and its corresponding protocol behavior.
