together with some minor polishing, this pr changes how a reduced bitmap gets transformed into an embroidery: Instead of simply taking the complete scan line of one color per bitmap row, we section out all "strands of colors" (connected pixels of same color) and sort them so that we minimize the amount of jumps between them.
The sorting compare the end of the current strand to all start and endpoints of remaining strands.
Once the closest remaining strand is found, it gets' determined, if the direction should be inverted: If the end point of the strand is the closest to our existing stitches, then the incoming new strand needs to be inverted.
Makes better looking stitches with less jumping.
