[Cin] Testing Nvidia Nvenc encoding

[Phyllis Smith]

Here is the AppImage with the latest nvencoders for Nvidia graphics that
goes with ffmpeg.
   https://cinelerra-gg.org/download/testing/cin-x86_64_nvencupdate.AppImage
For comparison, here is the appimage containing the original nvencoders
from 2020.
  https://cinelerra-gg.org/download/images/CinGG-20241031-x86_64.AppImage

I am not sure if encoding with formats h264_nvenc.mp4, h265_nvenc.mp4, or
h264_nvenc.qt actually work from an AppImage that was created on a computer
that does not have an Nvidea graphics card or its software.  But for some
reason, I do not think that that matters and it should work.
