Operations on moved segment still use its original position

[dgDSA]

After moving a Segment by (0, 0, -1), the "in" and "intersection" operations still take the original position into account.

s = Segment(Point(0, 0, 1), Point(2, 0, 1))
s.move(-z_unit_vector())
Segment(Point(0, 0, 0), Point(2, 0, 0))
s
Segment(Point(0, 0, 0), Point(2, 0, 0))
s2 = Segment(Point(0, 0, 0), Point(2, 0, 0))
s == s2
True
Point(1, 0, 0) in s2
True
Point(1, 0, 0) in s
False # Should return True
Point(1, 0, 1) in s
True # Should return False
ground = Plane(origin(), x_unit_vector(), y_unit_vector())
print(intersection(s2, ground))
Segment(Point(0, 0, 0), Point(2, 0, 0))
print(intersection(s, ground))
None # Should return the segment

This may be caused by a failure to move the "line" attribute accordingly:

s.line
Line(sv=Vector(0, 0, 1),dv=Vector(2, 0, 0))
s2.line
Line(sv=Vector(0, 0, 0),dv=Vector(2, 0, 0))

Doing Advent of Code? :)

I had the same problem yesterday trying to figure out the bug in my code as it wasn't working. It does indeed turn out that the function move on line 85 of segment.py doesn't move self.line, which in turn is used by intersection! I just added a self.line.move(v) and now everything works! Spent hours on that yesterday!
