Make number of frames taken into account by Artemis and others selectable

If I remember correctly, Artemis looks at 5 frames at a time, Proteus at 3… Don´t remember exactly…

In some cases, changing these numbers helps a lot for motion consistency and ghost details or stabilization of moving backgrounds - so maybe in an “advance tab”, a selection would be helpful.

Unfortunately, this cannot be done. This will require model redesign/training and so it won’t be Artemis or Proteus.
