Introduce screensaver support for Windows 10/11

[marcohoovy]

This partially completes #41 by adding screensaver support for Windows 10/11, this lacks the ability to close on mouse-movement.

This doesn't implement ScreenSaverProc but currently I don't see the need to add such functionality

i really like this, did the test on windows 10. mind if i push some commits to fix the pathing and interaction issues? @marcohoovy

current issues to address:

• notepad can't found the config if it doesn't exist

• preview is not showing correctly

• aside from close on mouse movement, maybe disabling the selection entirely?

Be my guest, Regarding the preview not working correctly, there is no CLI handling for that because windows returns a handle to the display that weathr must render into, I was unsure how to approach it to be honest
