Bitwise shuffle for two-way hashing

## Use (Deno)

```ts

import {shuffle, unshuffle, random} from "https://raw.githubusercontent.com/gnlow/bitwise-shuffle/master/mod.ts"

const key = [2, 0, 1, 3]

const hash = shuffle(key)

console.log(hash(0b1010)) // 6 = 0110(2)

/* 

input: 10 = 1010(2)

key:        2013

            \//|

            //\|

            ||||

output: 6 = 0110(2)

*/

const unhash = unshuffle(key)

console.log(unhash(0b0110)) // 10 = 1010(2)

console.log(random(4)) // (ex) [ 1, 0, 2, 3 ]

```
