Upgrade to CWL v1.2

[illusional]

With conditionals being released, it's time to upgrade Janis workflows to CWL v1.2. This shouldn't be a breaking change for workflows as there's no syntax change. It might break your engine if your engine doesn't correctly support CWL v1.2 - so it might be worth bumping Janis to v0.11.x.
