* @name bnToBn
* @summary Creates a BN value from a BN, bigint, string (base 10 or hex) or number input.
* @description
* `null` inputs returns a `0x0` result, BN values returns the value, numbers returns a BN representation.
* @example
* <BR>
*
* ```javascript
* import BN from 'bn.js';
* import { bnToBn } from '@polkadot/util';
*
* bnToBn(0x1234); // => BN(0x1234)
* bnToBn(new BN(0x1234)); // => BN(0x1234)
