pkv 05508ac895 decklink: Fix FC<->LFE channel swap for some devices
Fixes mantis issue https://obsproject.com/mantis/view.php?id=1379
For some devices with hdmi input, the Front Center channel and the LFE
channel are swapped. For some others they are not.
To solve the issue a new swap setting is added so that the user can
swap the two channels if needed.
