* @name u8aToBuffer
* @summary Creates a Buffer object from a hex string.
* @description
* `null` inputs returns an empty `Buffer` result. `UInt8Array` input values return the actual bytes value converted to a `Buffer`. Anything that is not a `UInt8Array` throws an error.
* @example
* <BR>
*
* ```javascript
* import { u8aToBuffer } from '@polkadot/util';
*
* console.log('Buffer', u8aToBuffer(new Uint8Array([1, 2, 3])));
