v1.0.2 - 07 May 2020
* Since 1.0.0, we took somet time to play the test coverage game.
The coverage is around 30% better, and we _did_ uncover some
inconsistencies in the API, which got promptly fixed.
But I'm tired of the coverage game for the time being. PR's welcome!
* Add jwk.AssignKeyID to automatically assign a `kid` field to a JWK
* Fix jwe.Encrypt / jwe.Decrypt to properly look at the `zip` field
* Change jwe.Message accessors to return []byte, not buffer.Buffer
