Fixes #398

https://github.com/xamarin/AndroidX/issues/821

After upgrading AndroidX packages in our Xamarin Forms Android project, the linker fails on LottieXamarin using some outdated version of AndroidX types.

Error Mono.Linker.MarkException: Error processing method: 'AndroidX.Collection.SparseArrayCompat Com.Airbnb.Lottie.LottieComposition::get_Characters()' in assembly: 'Lottie.Android.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve AndroidX.Collection.SparseArrayCompat

Changes

Update Xamarin.AndroidX.AppCompat from 1.3.1.3 to 1.6.1.6
Change Android target from monoandroid10.0 to monoandroid12.0 to support newest AndroidX package

Notes

This needs some assistance to fit into the latest changes of develop with net6.0 / maui. I'm not sure if this is experimental or not, but I was not able to build it.

The PR is currently based on the commit prior to net6.0 / maui update, since our team is currently stuck on standard Xamarin Forms for some time and it solves our need. Maybe we can multi-target both monoandroid12.0 and android-net6.0 to continue support for old Xamarin?

Just a heads up, but I will not be pursuing this PR as we switched to another library instead.

https://github.com/mono/SkiaSharp.Extended (must use prerelease nugets as of now)

This article was helpful although it explains for MAUI: https://cedricgabrang.medium.com/implementing-lottie-animations-in-your-net-maui-application-62bd484af651

I'll leave the PR open for anyone stumbling into this later or if you wish to take over the PR.
