Fix hyprctl Color and Icon problem

[ysekka]

I have told about on color problem before. They color codes had to be written in hex form, not rgb form.
I also found that there is no no-icon option. So I fix it too.

I understand that the notify command might not work with decimal number, but please keep the PR on topic, why are so many functions made public?

[ysekka]

Someone maybe wants to use those functions. For example, there is a guy who forked Hyprland and added some commands to it wants to interact with it by rust. That is clear that we cannot add every single commands of a hyprland fork to hyprland-rs. If someone wants to execute a custom command, he/she can do this. If a function which execute custom commands exists, I can make them pub(crate) again.

If they fork the repo, the functions will be available that's what pub(crate) means, it means it's available to the current crate? And I'm planning on introducing a better way of doing this that's more user oriented, so please reverse that. Also, please fix your commit names, this is a public project, such vague commit messages are not allowed. Preferably, make them into one through like a force push or something.

I converted all leftover pub's to pub(crate)s. I also fix the hex conversion and I replaced i8 with i32. I hope that I hadn't left anything.

The commit names are still not fixed
