Focus game window

[paoloambrosio]

Relates to #50.

Focus game window before applying pit strategy.

• It should be done at DeviceIO level.
• Do it if "enough time" has passed since last time and a key press needs to be sent.

Tried this but it didn't work reliably.

Dependency:

<ItemGroup>
  <PackageReference Include="PInvoke.User32" Version="0.7.124" />
</ItemGroup>

Code:

using System.Diagnostics;
using PInvoke;

// ...

if (Process.GetProcessesByName("AC2-Win64-Shipping").Take(1)
    .Where(process => User32.GetForegroundWindow() != process.MainWindowHandle)
    .Any(process => !User32.SetForegroundWindow(process.MainWindowHandle)))
{
    Console.WriteLine("FAILED TO SET FOREGROUND WINDOW");
}
