[decklinksrc] How to add 4k support

[Edward Hervey]

Hi,

  It *should* just be a matter of adding the proper lines for detecting
those modes and exposing proper caps (i.e. different
width/height/framerate..). 

  See gstdecklink.{cpp,h}, you should just have to add the proper lines
there.

  We track bugs and patches on bugzilla.gnome.org (product: GStreamer,
component: gst-plugins-bad). You're welcome to open a bug there and
provide your patches (or a link to a public git repository) there.

  I have this sneaking suspicion we're going to hit interesting
performance ""problems"" with this bitrate :)
