Add RequiresUnreferencedCode attribute for reflection code and add OverloadResolutionPriority attribute to prefer non-object methods

[Cheesebaron]

This PR adds RequiresUnreferencedCode attribute on methods that use reflection. This is primarily the convenience methods and extension methods that take an object like: new { hello = "world" } and turns it into a dictionary with key hello which will be equal to the string object "world".

Also added the IsTrimmable = true property on the project, which allows the compiler to trim the library.

For the extension methods that take the object as argument, I've also added the [OverloadResolutionPriority(-1)] attribute to make the compiler prefer the non object overloads.

Fixes #49

Unrelated, but I remember you from the Xamarin forums in the early days of Xamarin, back when I started learning C#, so it was funny to see @Cheesebaron aka Ostebaronen in my inbox again after all these years. 😄
