Fixes #1236.

This patch makes all header operations operate on bytes and converts all headers and values to bytes before operation. With a follow up patch to hpack it should also increase efficiency as currently, hpack casts everything to a str first before converting back to bytes: https://github.com/python-hyper/hpack/blob/02afcab28ca56eb5259904fd414baa89e9f50266/src/hpack/hpack.py#L150-L151

Note to reviewer: I'm aware there are formatting changes (they came from "format on save") and although I think things are more readable now, I'm happy to find and revert all unrelated formatting changes to make reviews easier.

Unfortunately, I realized the auto format changes way too late and wanted to get the patch up as promised first.

Alternatively, I can submit a PR that reformats the entire codebase without any changes and then rebase this on top of that.

Fixed format-related things mostly. I think we should still do a full repo black to make it easier for future contributors.

Fixes python-hyper#1236.

Please keep the changes in each PR to a minimum - in this case please revert the style-related changes.
Discussing coding style is outside of the scope here.

@Kriechi we should be good now, sorry for the trouble.

I'm contemplating making the encoding of headers part of the normalization pipeline, instead of being the responsibility of the outside caller.

What do you think about integrating it here?

That's exactly what I wanted but unfortunately we have an option to bypass normalization, which breaks that neat abstraction :(
