Fix axis mismatch on show/hide of sensor arrows

[Alexboiboi]

This fixes the mismatch of showed or hidden sensor axes. More specifically the "y" and"z" where switched when trying to hide one.

I would suggest to do a patch fix release right away when this is merged. I'd have a workaround for a Left Handed Sensor which needs this fix (see #676)

import magpylib as magpy

sens = []
for i, k in enumerate("xyz"):
    s = magpy.Sensor(
        position=(i, 0, 0),
        style_label=f"Sensor ({k}-axis hidden)",
        style_size=4,
    )
    s.style.arrows.update({f"{k}_show": False})
    sens.append(s)
magpy.show(sens)
