switch to pinhead

[dschep]

Pinhead is a giant map-focused iconset which inclues all of maki and the overwhelming majority of temaki(and certainly everything relevant to this repo). This PR switches the maki_temaki field to a pinhead field. Also updates the ultra query to match (and actually work, i'd broken it due to changes in ultra 🫣 )

Used waysidemapping/pinhead#105 with this little script:

import fs from "node:fs";
import { migrateName } from "@waysidemapping/pinhead-js";

const landmarks = JSON.parse(fs.readFileSync("landmarks.json"));

for (const l of landmarks) {
  const [iconset, name] = l.maki_temaki.split("/", 2);
  l.pinhead = migrateName(name, iconset);
  delete l.maki_temaki
}

fs.writeFileSync("landmarks.json", JSON.stringify(landmarks, null, 4))
