Reload hotkey

[SeamusTheHunter]

Since iCUE breaks every time you go to the lock screen and the ambilight plugin has to be reloaded (which you already made super convenient via the taskbar tray, thank you!), it'd be sick if you could add hotkey support so reloading each time one logs in would as simple as the press of a button.

Thanks again for creating this! It's the least intensive program for ambilight keyboard effects that I've found, and it updates super smoothly. Love ya 💚
