Subject: [PATCH] Avoid "XamlExplorerHostIslandWindow" issues & Support for
 Insider Build (#1210)

* Updated the toolkit

Microsoft deprecated the old toolkit and released the same thing under a new name.

* Update ModernFlyouts.Package.wapproj

* Update README.md

* Extra check for volume OSD

- Checks the band the window is on to make sure that it is the volume bar

* Fixes Windows 25000 Builds

Allows flyout window to be painted without using a plane (or whatever it's called) so it can run on Windows Canary Builds.

* Revert README.md

* Revert name
