Deno support?

Does anybody have experience getting this to run in Deno?

My output is constantly looking like this

```
Uint8Array(24) [
0, 0, 0, 7, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0
]
```

While my input looks like this

```
ArrayBuffer {
[Uint8Contents]: ,
byteLength: 3243
}
```

I've been trying to get this to work for a few days now. Wondering how this works in Deno as it works perfectly fine in NodeJS. Maybe due to the Buffer object
