draw_cable_auto() + Meander() port orientation

[phelyx42]

What

only vaild in HFSSdrawpy/alice_et_bob

the stretch parameter in Meander gives different results depending on the port orientation

minimum Example

import os
from HFSSdrawpy import Body, Modeler
from HFSSdrawpy.parameters import DEFAULT, GAP, TRACK
from HFSSdrawpy.path_finding.path_finder_auto import Meander

pm = Modeler('gds')
chip = Body(pm, 'chip')

positions = [
    [[-0.5e-3, 0.5e-3], [-1,0]],
    [[-0.5e-3, -0.5e-3], [-1,0]],
    [[0.5e-3, 0.5e-3], [1,0]],
    [[0.5e-3, -0.5e-3], [1,0]],
]

ports = []
for ii, pos in enumerate(positions):
    with chip(pos[0], pos[1]):
        ports += chip.port(widths=[10e-6], name=f'port_{ii}')

meander = Meander(index=1, n=3, pos=0.5, stretch=True)
chip.draw_cable_auto(ports[0], ports[1].r, name='cable1', fillet=40e-6, meanders=[meander], target_length=3e-3)
chip.draw_cable_auto(ports[2], ports[3].r, name='cable2', fillet=40e-6, meanders=[meander], target_length=3e-3)

chip.generate_gds(os.getcwd(), 'pathfinding')
