neat, no more passing the event loop around 👍

can you run the cs fixer, or apply the reported changes by hand please?

Sure let me fix those.

There is one more thing to consider. And that is that the event loop isn't needed anymore in this pack even for the HTTP client. The same Loop::get() is used internally there when no event loop is provided. And since async and await also do that it can be removed there as well. (Already prepaeed a branch for that if you want to do that.)

Opened the client changes in draft over at #58 It would require this one to be merged first.
