* @name u8aToU8a
* @summary Creates a Uint8Array value from a Uint8Array, Buffer, string or hex input.
* @description
* `null` or `undefined` inputs returns a `[]` result, Uint8Array values returns the value, hex strings returns a Uint8Array representation.
* If `strict` is true, `null` or `undefined` will throw an error instead of returning an empty array.
* Supports input types: Uint8Array, Buffer, hex string, string, or number array.
* @example
* <BR>
*
* ```javascript
* import { u8aToU8a } from '@polkadot/util';
*
* u8aToU8a(new Uint8Array([0x12, 0x34]); // => Uint8Array([0x12, 0x34])
* u8aToU8a(0x1234); // => Uint8Array([0x12, 0x34])
* ```
