I added minor stuff. Rest of changes LGTM. Great job, @sergio-correia
When we have "zip" in the protected header, e.g.: "zip": "DEF", we should compress the payload before the encryption. However, as it stands, we are doing the compression after the encryption, which results in the jose_jwe_enc* functions producing JWEs that we are unable to decrypt afterwards. For the "zip" case, we do the compression now before the encryption, to fix this behavior. Also add some tests to exercise these scenarios, both using the jose_jwe_enc*/jose_jwe_dec* functions, as well as the command line utilities jose jwe enc / jose jwe dec.
