Module support

[kraxarn]

nakama-js seems to stop working once a project uses ES6 modules. For example, simply doing this:

import { Client } from "@heroiclabs/nakama-js"
const client = new Client()

Results in error:

import { Client } from "@heroiclabs/nakama-js";
         ^^^^^^
SyntaxError: Named export 'Client' not found. The requested module '@heroiclabs/nakama-js' is a CommonJS module, which may not support all module.exports as named exports.

It instead suggests importing it like:

import nakama from "@heroiclabs/nakama-js"
const {Client} = nakama

But that instead throws another error:

   import nakama from "@heroiclabs/nakama-js"
          ^
   const { Client } = nakama
> 'default' is not exported by node_modules/@heroiclabs/nakama-js/dist/nakama-js.esm.js

Seems to be related to using TypeScript with "module": "es2020".

@kraxarn Thanks for the issue report. I'm not familiar with how the TypeScript "module": "es2020" affects a project built with ES6 modules. Can you suggest how it should be updated?

Tested the solution from #108 and can confirm it works fine now.
@bluwy Thank you for looking into this!

@bluwy I have seen your name pop up so many times. Thank you for your contributions to Vite and Svelte!

Would you consider chiming in here to help us figure out how to make this library work with SvelteKit?

Thank you!
