 * Convert a time series to a weekly frequency. Default: all days

 * @param nd array of unix dates

 * @return matrix of weekly dates and values
 *
 * @example Convert daily data to weekly frequency (simplified)
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * const dates = [1421280000, 1421366400, 1421452800, 1421539200];
 * const values = [100, 99, 102, 103];
 * const result = toweekly(dates, values);
 * assertEquals(result.length, 2);  // Returns [dates, values] array
