 * Convert a return series to a value series with a start value.
 *
 * Converts a return series to a value series (prices) given a starting value.
 * Can handle both simple and continuous (log) returns.
 *
 * @param x Array of returns
 * @param mode Method to compute values: 'simple' or 'continuous' (defaults to 'simple')
 * @param sval Starting value (defaults to 1)
 * @param dim Dimension to operate on (0: row-wise, 1: column-wise) (defaults to 0)
 * @returns Value series (prices)
 * @throws If unknown return method specified
 *
 * @example Converting returns to prices with a custom start value
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(ret2tick([0.5, -0.5, 1.0], 'simple', 100), [100, 150, 75, 150]);

 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(ret2tick([0.1, -0.05, 0.2], 'continuous', 100), [100, 110.51709180756477, 105.12710963760242, 128.40254166877418]);
