Detect image type and size using pure javascript.

## Usage

Install package:

```sh
# npm
npm install image-meta

# yarn
yarn add image-meta

# pnpm
pnpm install image-meta

# bun
bun install image-meta
```

```ts
import { imageMeta } from "image-meta";

const data = await fetch(url).then((res) => res.buffer());

// Meta contains { type, width?, height?, orientation? }
const meta = imageMeta(data);
```

**Note:** `imageMeta` throws an error if either data is not a `Buffer`/`Uint8Array`, or data is invalid or type cannot be determined. You should wrap it into a `try/catch` statement to handle errors.
