[Rebased] Support for custom HTTP headers

[bpolaszek]

Hello @clue,

This one is a rebased version of #10. When you've got some little time, could you please review this?
If you merge, please co-author @qharnay since he did the biggest part of the job :-)

Do you plan to tag a 0.1? I'll soon require that dependency on a production app (server listening to a Mercure server, with authentication) and even if not considered stable, at least avoid relying dev-master in case of breaking changes.

Thank you much!
Ben

Time to ping again - @clue could you please review?

@bpolaszek Thanks for looking into this and the friendly reminder! I'm currently in the process of applying some major upgrades to @reactphp that will also affect this project here. Once this done, I'll make sure take a look at this again as soon as time permits 👍

[bpolaszek]

@clue No worries 🙂 I assume you're kinda busy with X-Framework 🍿

No emergency on my side, I'll ping you again in a few months when I'll cleanup my forks 😄

@bpolaszek I continued the conversation in #10 👍

I've just filed reactphp/http#449 as a way to keep track of this ticket upstream and believe this is the best way to address this 👍

In the meantime, I'll assume this one is resolved and will close this for now, please feel free to report back otherwise 👍
