feat: add `newLogs` event to `WebSocketProvider`

[sarvalabs-harshrastogi]

This pull request introduces a new newLogs event to the WebSocketProvider class. This enhancement allows for real-time emission of logs that match specified filters, improving our ability to handle and respond to blockchain events efficiently.

Example

import { WebSocketEvents, WebSocketProvider } from "js-moi-sdk";

const ws = new WebSocketProvider("ws://141.94.161.24:1602/ws");

ws.on(WebSocketEvents.CONNECT, () => {
  console.log("Connected to the WebSocket server");
});

const logEvent = {
  address: "0xb90f39fcf346ba3260518669495f5d368a8d1bb8023584f67e8a5671cf3c56ce",
  topics: [],
  height: [-1, -1],
};

ws.on(logEvent, (response) => console.log(response));
