Replace ffmpeg-ndi with gst-plugin-ndi for ndi-feeder.
We can no longer reliably compile ffmpeg with the NDI reversal patch. While gst-plugin-ndi isn't particularly well maintained anymore either, it works for now and will probably become a main-stay in my setup. The alternative is doing NDI via OBS and that's just silly and not easily automatable.main
