A header-only helper for initializing WinRT objects that requires a hwnd.

To use, simply change the namespace winrt to WinUIEssentials of your objects that needs to be initialized, and pass either a HWND or a Microsoft.UI.Xaml.Window to the constructor.

Take FileOpenPicker as an example:

#include <include/IInitializeWithWindowHelper.hpp>

WinUIEssentials::Windows::Storage::Pickers::FileOpenPicker picker{ MainWindow::Hwnd };
//or
WinUIEssentials::Windows::Storage::Pickers::FileOpenPicker picker{ MainWindow::Instance };

//...
picker.PickSingleFileAsync();
