Updated to Stride 4

Works now with Stride.

• Parses all shaders in user.nuget\packages\stride.packagename\latest-version
• To view the shaders of a local source repo either set the StrideDir environment variable to the source repo main dir or select it via folder browser

Make sure Stride is installed, then just extract and run the exe. You can pin it to the taskbar if you use it frequently.
