+ * @name hexToU8a
+ * @summary Creates a Uint8Array object from a hex string.
+ * @description
+ * `null` inputs returns an empty `Uint8Array` result. Hex input values return the actual bytes value converted to a Uint8Array. Anything that is not a hex string (including the `0x` prefix) throws an error.
+ * @example
+ * <BR>
+ *
+ * ```javascript
+ * import { hexToU8a } from '@pezkuwi/util';
+ *
+ * hexToU8a('0x80001f'); // Uint8Array([0x80, 0x00, 0x1f])
+ * hexToU8a('0x80001f', 32); // Uint8Array([0x00, 0x80, 0x00, 0x1f])
+ * ```
