Tested out median, I think it has a little edge compared to average, you get some fine noise/grain in the frame which gives it a little more sharpness perception.

I have uploaded all the 16 aligned PNG files, and the original PPM file for this particular frame on google drive:
Just in case you come up with some other methods of combining those 17 frames ;)

I've also included the average and the Median files on google drive

@Levas
For comparison reasons I tested your png files by transcoding them to tiffs and ran them against this script(enfuse/hugin). It will average 6 files not all the 17 png files:
