Add support for adding VANC packets to decklink frames

Separate Vanc class that handles vanc related logic
Strategy based approach to isolate different types of ancilliary data
Only support for a push based workflow atm (via amcp APPLY, se separate PR amcp: add APPLY command, similar to CALL but for consumers #1638 ), but should be fairly easy to extend with support for data arriving from other sources (ie. the producer/consumer-pipeline)
