Add 3 pixels to edge margin for guide star selection (4.3.x patch)

This PR makes a new characteristics value proseco.characteristics_guide.CCD['guide_extra_pad'] that is set to 3 pixels. This is used in guide star selection as part of the initial filter on stars so these stars that do not have at least these 3 extra pixels margin from the dither padded + window padded + (row/col) padded edge will not make the initial cut of candidates.

What's driving the new thing I've seen in your code of row_max * -1 instead of -row_max? I think the latter is fine and readable.

The only thing driving it (here) is a copy of the test that was already there. (whether or not I unconsciously find the negative more noticeable on row_max * -1 than -row_max is a different question and I have no answer).
