feat: add gallery button on qr to pick images

[Abhijeet6395]

Added a gallery button that can access the gallery and pick images, to make sure that people can pick qr from gallery as well.

android.permission.READ_EXTERNAL_STORAGE is used to target API's below 33.

@Abhijeet6395 Can you reiterate in this. I don't think you need READ_EXTERNAL_STORAGE permission for this.

@G00fY2 Thanks for the aweesome library you've put out in open! We are using your library in our organization's app and we needed this import from gallery feature.

@Abhijeet6395 We can make the visibility of Gallery button configurable by passing an input to ScanQRCode ActivityResultContract.
