Support Pyodide (Jupyterlite)

### Is your feature request related to a problem?

I'm a contributor to [Panel](https://panel.holoviz.org/) which can run on many platforms including [Panelite](https://panelite.holoviz.org/lab/index.html) (~Jupyterlite). We would like to be able to use Jupyterlite to provide an easy to use platform to showcase our framework and help our users learn how to use it.

I believe this is a general trend in Python that frameworks and users start moving to the browser powered by Pyodide, PyScript and Jupyterlite for education and for lighter data analytics.

One of Panels reference notebooks shows how to use Panel with async and `aiohttp`. The problem is that I cannot import `aiohttp` with piplite.

You can **reproduce** as described below

- Open Jupyterlite https://jupyterlite.readthedocs.io/en/latest/_static/lab/index.html
- Open a Pyodide notebook
- Run the code below

```python
import piplite
await piplite.install(['aiohttp'])
```


```python

### Describe the solution you'd like

That I can import **and use** `aiohttp` in Pyodide and Jupyterlite.

### Describe alternatives you've considered

Removing the `aiohttp` notebook from the Panelite example notebooks.

### Related component

Client

### Additional context

When the import problem has been solved there is probably a lot more to solve to get aiohttp working.

The code we are using is

```python
async def get_img(index):
async with aiohttp.ClientSession() as session:
async with session.get(f"https://picsum.photos/800/300?image={index}") as resp:
return await resp.read()
```

I can see that `multidict` can be imported by it self. Its the version pinned that is the import problem.
