warning "was never awaited" when using README example

[sarah-github]

Hi,
when using the example from your README, the following warning occurs:

uplink_httpx/client.py:39: RuntimeWarning: coroutine 'AsyncClient.aclose' was never awaited pass RuntimeWarning: Enable tracemalloc to get the object allocation traceback

This is concerning the line

asyncio.create_task(self._session.aclose())

in client.py, the self._session.aclose() should be awaited, but then, also the whole __del__ function has to be async which creates further needs of changes. Is this because of newer versions of uplink and httpx, since the example was created?

Not sure, if it's the proper solution, but asyncio.run instead of asyncio.create_task avoids the warning.
