Thanks for the comment, Mark. Indeed this may not be helpful for people who did not know the background of such parameters. I added more details to it so people could understand the trade-off behind it better. Will re-submit the patch soon.

Add the option to use -enable-keyframe-filtering with libaom-av1 codec. The option controls the encoder behavior on performing temporal filtering on keyframes.
