Added Activation with time @ startup of the program

[MrSloth-dev]

Added a paramater of '-ti' or '--time' that receives the dawn and sunset hour in HH:MM format (24hours) and then converts to float so that you can compare with the actual time. then it activates the identity matrix (or not) according to time.

I tried to minimize the impact of the current code to help the review.

If continuous monitoring (run the program once and when the sunset arrives it activates) is needed/wanted, then it needs to change the main stucture of the code( as far as i know) to encapsulate the screen change in a function so that it can runs on a loop ( maybe integrate in wayland loop?).

    while (wl_display_dispatch(state.wlDisplay) != -1) {
        monitorAndUpdate(dawn,  sunset,  KELVIN, std::ref(identity));
        ;
    }

Best regards and thank you for this little program. Happy to contribute.

It is wanted (I believe without it this is quite useless) but the method you're thinking of is wrong. See https://github.com/hyprwm/hyprlock/blob/cc7ffe73e7588137eb239239da0d83fe334b3ddd/src/core/hyprlock.cpp#L433-L583

it might be out of your scope (idk your C++ proficiency) but if you're up to the challenge feel free to implement this. Probably need to move hyprsunset into a singleton to stay on point with our code style (see g_pHyprlock, in that case)

I'm more a C guy, but in my spare time I will search about what you asking and if I get somewhere I'll let you know. In meantime I think my present proposal al least can be used for later iterations. Good work :)
