Expose request ids used by WebSocketProvider

[naddison36]

Can the WebSocketProvider class expose the ids of its requests? This is handy for correlating requests with responses in application logs.

Two ways this can be done are:

1. Move the NextId variable to a readonly property on the WebSocketProvider class
   

   ethers.js/packages/providers/src.ts/websocket-provider.ts

   Line 31 in 5fcd03f

   let NextId = 1;

2. Just use _nextId on the JsonRpcProvider class that WebSocketProvider extends.
   

   ethers.js/packages/providers/src.ts/json-rpc-provider.ts

   Line 224 in 5fcd03f

   _nextId: number;

Here's an example from my extension of the JsonRpcProvider class

	public async send(method: string, params: any): Promise<any> {
        const requestId = this._nextId
        logger.debug(`About to send JSON-RPC request`, {
            method,
            params,
            id: this._nextId,
        })
        const response = await super.send(method, params)
        logger.debug(`JSON RPC response`, {
            method,
            response,
            id: requestId,
        })
        return response
    }

You are correct, I should mimic the JsonRpcProvider.send logic in the WebScoket.send.

I'll add that soon. :)

This has been added in 5.0.17. Try it out and let me know how it works for you. :)
