@Julusian this is a follow-up of the discussion in #1749.

I've figured it's probably better to keep this as a separate consumer.

I've decoupled the ArtNet sink and made it easy to add other types of sinks in the future.

This adds a few interesting possibilities. First, we can add other output protocols, such as sACN (E1.31). Or, we can add a pipe as a sink and output raw pixel data for processing by external tools. This makes CasparCG act as a compositing engine. And so on.
