Callback output, split SDK

• Add a callback output for pull-based components without time step
• Add property is_push_based to IOutput to indicate if data must be pushed
• Handle pull-based inputs in ConnectHelper/try_connect
• Log warning when a time component was not updated during a run
• Split module sdk, as it exceeded 1000 lines of code
• Add tests

Fixes #22 (closed)

Pull-based components/outputs offer one more way to build non-working compositions. We should check for them! Continued in #49 (closed).
