`num_frames` indicates the total number of frames in the animation. This must equal the number of `fcTL` chunks. 0 is not a valid value. 1 is a valid value for a single-frame APNG. If this value does not equal the actual number of frames it should be treated as an error. | `num_frames` indicates the total number of frames in the animation.
