/**
 * Create an Osm index from GeoParquet data.
 *
 * Accepts various input formats (file path, URL, or buffer) and converts
 * features to OSM entities:
 * - Point → Node
 * - LineString → Way with nodes
 * - Polygon → Way (simple) or Relation (with holes)
 * - MultiPolygon → Relation
 *
 * Feature IDs are preserved if available; otherwise sequential negative IDs
 * are assigned. Feature tags become OSM tags.
 *
 * @param source - GeoParquet data source (file path, URL, or buffer)
 * @param options - Osm index options (id, header)
 * @param readOptions - Options for reading the parquet file
 * @param onProgress - Progress callback for UI feedback
 * @returns Populated Osm index with built indexes
 *
 * @example
 * ```ts
 * import { fromGeoParquet } from "@osmix/geoparquet"
 *
 * // From file
 * const osm = await fromGeoParquet("./roads.parquet")
 *
 * // Query the imported data
 * const highways = osm.ways.search("highway")
 * ```
