Add bbox search

[bkeepers]

You can find all stations within a geographic bounding box using the bbox function:

import { bbox } from "@neaps/tide-database";

// Find stations in the Boston area
const stations = bbox(-71.5, 42, -70.5, 42.8);
console.log("Stations in bounds:", stations.length);

// With a filter
const referenceOnly = bbox(-72, 41, -70, 43, (station) => station.type === "reference");
