Bug: kicad: transformer: round_corners is broken

[ruben-iteng]

Current Behaviour

faebryk/src/faebryk/exporters/pcb/kicad/transformer.py

Lines 863 to 885 in 60856b7

	def round_corners(
	self, geometry: Sequence[Geom], corner_radius_mm: float
	) -> list[Geom]:
	"""
	Round the corners of a geometry by replacing line pairs with arcs.
	"""
	def _transform(geo1: Geom, geo2: Geom) -> Iterable[Geom]:
	if not isinstance(geo1, Line) or not isinstance(geo2, Line):
	return (geo1,)
	new_line1, arc, new_line2 = self.connect_line_pair_via_radius(
	geo1,
	geo2,
	corner_radius_mm,
	)
	return new_line1, new_line2, arc
	return [
	t_geo
	for pair in pairwise(list(geometry) + [geometry[0]])
	for t_geo in _transform(*pair)
	]

produces unusable output:

Expected Behaviour

_transform function should use previous generated lines as input lines for next iteration.

lineA-lineB > _transform > lineAarced-arc-lineBarced
lineBarced-lineC > _transform ...

So the result will look like this:
