## Usage
#### Encoding
```swift
let image = UIImage(named: "demo")
let encoder = WebPEncoder()
let queue = DispatchQueue(label: "me.ainam.webp")
// should encode in background
queue.async {
let data = try! encoder.encode(image, config: .preset(.picture, quality: 95))
// using webp binary data...
}
```
#### Decoding
```swift
let data: Data = loadWebPData()
let encoder = WebPDecoder()
let queue = DispatchQueue(label: "me.ainam.webp")
// should decode in background
queue.async {
var options = WebPDecoderOptions()
options.scaledWidth = Int(originalWidth / 2)
options.scaledHeight = Int(originalHeight / 2)
let cgImage = try! decoder.decode(data, options: options)
let webpImage = UIImage(cgImage: cgImage)
DispatchQueue.main.async {
self.imageView.image = webpImage
}
}
```
