Implement support for including AFD in decklink output when putting
out 10-bit VANC data.
Updated to reflect feedback in 2018 from Marton Balint <cus@passwd.hu>,
Carl Eugen Hoyos <ceffmpeg@gmail.com> and Aaron Levinson
<alevinsn_dev@levland.net>. Also includes fixes to set the AR field
based on the SAR, as well as now sending the AFD info in both fields
for interlaced formats.
