fix(cropper): remove deprecated variables

BREAKING CHANGES:

`cropperEvent.base64` is now deprecated, use `cropperEvent.dataURL` instead

before:

```ts
onCropped(e: ImgCropperEvent) {
  this.croppedImage = e.base64;
}
```

after:

```ts
onCropped(e: ImgCropperEvent) {
  this.croppedImage = e.dataUrl;
}
```
