isomorphic hex library in 256 bytes

## Install

`npm install hex-lite`

## Usage

```javascript
const hex = require('hex-lite')

hex.toUint8Array('000f10ff000f10')
// new Uint8Array([0,15,16,255,0,15,16])

hex.fromUint8Array(new Uint8Array([0,15,16,255,0,15,16]))
// '000f10ff000f10'

hex.toBuffer('000f10ff000f10')
// ArrayBuffer

hex.fromBuffer(new Uint8Array([0,15,16,255,0,15,16]).buffer)
// '000f10ff000f10'
```

## Can it be smaller?

If you use ES6 imports with a bundler that supports tree-shaking, yes!

```javascript
import { fromUint8Array } from 'hex-lite'
```

## I wanna go fast!

The Node implementation is just a proxy to Node's `Buffer` object to be as fast as possible. The default browser implementation optimizes for size, so if you're looking for raw speed, import like this:

```javascript
import hex from 'hex-lite/fast/hex-lite.mjs'
```
