1.0 - Update to WinUI 3

BIG UPDATE!
Now using WInUI 3 instead of WinForms. I have also added more features, for example, automatically changing to best performance when load on the deticated GPU is detected. However, this only works on NVIDIA GPUs so far.

If you are using Windows 10, you will have to download the Segoe Fluent Icons Font. You can get it here:

Since I have not tested this app on Windows 10, I can not guarantee that it works.

If you enconter any issue, please let me know by creating a new issue here on GitHub
