Add line.scale()-scale_ip() functions

For this function, we should specify where the origin of the scale will be, such as maybe the midpoint, startpoint, or endpoint in the function parameters.

Line.scale(origin: float, modifier: float)

a.scale(0, 5) # scales from startpoint
a.scale(0.5, 5) # scales from midpoint
a.scale(1, 5) # scales from endpoint
