David Stadelmann 1f247c2efc feat: add u-shape wire-style
Add the "u-shape" wire style, which connects two ports facing the same
cardinal side with a U-shaped bend. `u-side` selects the side and is
auto-detected from the port anchors with `detect-port-side` when set to
`auto`. `u-depth` sets the distance of the bend from the outermost
endpoint.

Add `u-at` for anchor-based placement of the crossbar, analogous to
`zigzag-at`. It overrides `u-depth`, which defaults to `auto` so the two
are mutually exclusive.

Add the `u-shape-wire` and `u-at` examples, extend the `wires` example
and add the `gallery/test_ushape` gallery entry.
