Support for WebSocket RPCs

[metalboyrick]

We would like to use this issue to request support for Starknet JSON RPC v0.8.0 WebSocket Channel in addition to existing HTTP RPCs, in particular adding it to the chain configurations so that we have a streamlined way of incorporating websocket RPCs.

It has been implemented on starknet.js.

• https://starknetjs.com/docs/next/guides/websocket_channel
• https://github.com/starkware-libs/starknet-specs/blob/v0.8.0/api/starknet_ws_api.json

We believe this would be useful for event listening and other real-time needs!

GM, are there any updates on this ser?

My understanding is that the websocket channel is not a provider like the others so we need to add another configuration object for it.
