Rectangle Detection Not Working on Android

[rosentoshev]

I managed to get the @wooinvers/react-native-document-scanner to work with both iOS and Android by changing and customising a couple of things. While I have no issue on how the library works on iOS, I am having an issue on Android. The rectangle detection would not work at all. I created a prototype with the `react-native-document-scanner, which is in this link: https://github.com/rosenexpend/ScannerImageCropper
