Async / await support

[badevilerror]

I'm unable to make my Lua / MoonSharp code to work with C# async / await.

What i've tried is basically:

async void Test1() {
   await SomethingAsync();
}

async Task Test2() {
   await SomethingAsync();
}

When calling those methods from Lua - async void has no effect, script just go on, without awaiting; and async Task throws an exception: ScriptRuntimeException: cannot convert clr type System.Threading.Tasks.Task`1[System.Threading.Tasks.VoidTaskResult] MoonSharp.Interpreter.Interop.Converters.ClrToScriptConversions.ObjectToDynValue

For the time being i'm using callbacks as a workaround, but i don't feel that's a good solution. For example using a C# async method with a callback makes the whole Lua script an async one - now also C# method is not awaiting.

As far as i can see there's also Function.CallAsync() but it's not working for me, as Unity is throwing exceptions about using it's apis from different threads.

Dunno, maybe it's me being stupid, but i don't know how to make it work.

I've also made a question on SO but it looks like nobody knows.
