Release 2.0

[froth]

We will need to release a new major version, to ship the changes in #452.

To do so I created a new branch series/2.x. @gvolpe could you change the github settings so that this is the new default branch?
I think that I did the needed changes so that the new branch can release artefacts in bbd7b8e if something is missing a hint would be appreciated :)

I will release a (hopefully) last 1.x version once sonatype is alive again. (done https://github.com/profunktor/http4s-jwt-auth/releases/tag/v1.2.3)

Additionally, we should think about other breaking changes that could be made, now that we have a major release coming up anyways.

I will leave this issue open for some time, so that there is a chance that other breaking ideas can come in.
