### Usage

```js

// ES6 imports

import { LEB128 } from '@minhducsun2002/leb128';

// CommonJS thingy

const { LEB128 } = require('@minhducsun2002/leb128');

// Unsigned integers

var a = LEB128.encode(462644);

// Uint8Array (3) [ 180, 158, 28 ]

var b = LEB128.decode(a);

// 462644

var c = LEB128.decode([0xA6, 0x87, 0x90, 0x04])

// 8651686

// Signed (negative) integers

var d = LEB128.encode(-128383);

// Uint8Array(3) [ 129, 149, 120 ]

var e = LEB128.decode(d, 0, true); /* offset = 0, negative number */

// 8651686

var f = LEB128.decode([0x01, 0x81, 0x95, 0x78], 1, true)

// -128383
