/**
 * Convert bytes to strings with units (KB, MB, GB, etc.).
 * @param {string|number} bytes Bytes.
 * @param {number} decimals Number of decimal places. Default is 2.
 * @param {boolean} asString If true, returns a formatted string; if false, returns an object with val and unit properties. Default is false.
 * @return {string|{val: number, unit: string}} Formatted value with units.
 * @example
 * ```js
 * import {utils} from 'metronic-extension';
 *
 * utils.formatBytes(435, 2, true);// -> '435 Bytes'
 * utils.formatBytes(490398, 2, true);// -> '478.9 KB'
 * utils.formatBytes(23483023, 2, true);// -> '22.4 MB'
 * utils.formatBytes(30498505889, 2, true);// -> '28.4 GB'
 * utils.formatBytes(9485039485039445, 2, true);// -> '8.42 PB'
 * utils.formatBytes(9485039485039445);// -> {val: 8.42, unit: 'PB'}
 * ```
