Porting the project to Xamarin Android .NET

[acaliaro]

Hi. I have created a Xamarin Android Binding Library to port the project to .NET for Xamarin Android.

https://github.com/acaliaro/ZxingAndroidEmbeddedDotNet

if anyone is interested in helping to complete the implementation, please come forward.
One of the things I noticed is that it is not possible to manage the reading screen of the barcode in portrait.
I had to exclude some classes as it gave error in the generation of the dll.

Even the installation of ScanContract I could not implement it because I can not manage ActivityResultContract <ScanOptions, ScanIntentResult>

It would be interesting to also bring the current JAVA examples in C #
