Please upgrade jose package

@rbellens, Because of dependency on X.509 which was throwing warnings:

firebase_dart also suffers from it.

Since jose has been already published by you (https://github.com/appsup-dart/jose/issues/53) could you please also upgrade firebase_dart? We'd also love to see intl and http packages upgraded.

Thank you in advance

firebase_dart has a dependency on jose: ^0.3.2. Which means that the latest version of jose, v0.3.4, is also allowed. So, simply running dart pub upgrade should do the trick for you.
