* Upgrade to 81.3.20-pre
* WinForms/WPF - Update enable-media-stream command line arg
Remove the "1" as it's not required, does nothing, there is no need to pass in a second argument
Issue https://github.com/cefsharp/CefSharp/issues/2858
* Upgrade to 81.3.100
Eliminates the requirements for .Net 4.5.2, the application exe is used as the browsersubprocess.
Additional manual import of CefSharp.BrowserSubProcess.Core is required see csproj file for example
TODO: OffScreen version is crashing on exit so it's been updated, it just isn't using itself as the BrowserSubProcess
