/**
 * Use a Barcode Scanner {@linkcode CameraOutput}.
 *
 * The Barcode Scanner {@linkcode CameraOutput} can be
 * attached to a {@linkcode CameraSession} or {@linkcode Camera}
 * component.
 *
 * @example
 * Attach to a `<Camera />` component:
 * ```tsx
 * const device = ...
 * const scannerOutput = useBarcodeScannerOutput({
 *   barcodeFormats: ['all'],
 *   onBarcodeScanned(barcodes) {
 *     console.log(`Scanned ${barcodes.length} barcodes!`)
 *   },
 *   onError(error) {
 *     console.error(`Failed to scan barcodes!`, error)
 *   }
 * })
 *
 * return (
 *   <Camera
 *     isActive={true}
 *     device={device}
 *     outputs={[scannerOutput]}
 *   />
 * )
 * ```
 * @example
 * Attach to a `CameraSession`:
 * ```ts
 * const device = ...
 * const scannerOutput = useBarcodeScannerOutput({
 *   barcodeFormats: ['all'],
 *   onBarcodeScanned(barcodes) {
 *     console.log(`Scanned ${barcodes.length} barcodes!`)
 *   },
 *   onError(error) {
 *     console.error(`Failed to scan barcodes!`, error)
 *   }
 * })
 * const camera = useCamera({
 *   isActive: true,
 *   device: device,
 *   outputs: [scannerOutput]
 * })
