ZoomImage generates some logs during its run, which can help you find the problem when something
goes wrong and help you understand it
How ZoomImage works.

### Logger

The [Logger] class encapsulates the print, level control, and output pipelines of logs

#### level

The [Logger].level property controls the print level of the log, the default is INFO, you can modify
it to expand the output range of the log

Example:

```kotlin
val zoomState: ZoomState by rememberSketchZoomState()

zoomState.logger.level = Logger.DEBUG

SketchZoomAsyncImage(
    uri = "https://sample.com/sample.jpeg",
    contentDescription = "view image",
    modifier = Modifier.fillMaxSize(),
    zoomState = zoomState,
)
```

#### pipeline

The [Logger].pipeline property controls the output pipeline of the log, and the default is
AndroidLogPipeline to output to Android
console, you can modify it to output logs elsewhere

Example:

```kotlin
val zoomState: ZoomState by rememberSketchZoomState()

zoomState.logger.pipeline = MyLoggerPipeline()

SketchZoomAsyncImage(
    uri = "https://sample.com/sample.jpeg",
    contentDescription = "view image",
    modifier = Modifier.fillMaxSize(),
    zoomState = zoomState,
)
```
