A simple wasm png encoder/decoder module for deno using wasm.

## Examples

### Decoding

```ts

import { decode } from "https://deno.land/x/pngs/mod.ts";

const file = await Deno.readFile("image.png");

console.log(decode(file));

```

### Encoding

```ts

import { encode } from "https://deno.land/x/pngs/mod.ts";

// An array containing a RGBA sequence where the first pixel is red and second is black

const data = new Uint8Array([255, 0, 0, 255, 0, 0, 0, 255]);

// Encode the image to have width 2 and height 1 pixel

const png = encode(data, 2, 1);

await Deno.writeFile("image.png", png);

```
