[Draft] Added version check, annotation tools, viewport (all screens) capture, no copy to clipboard parameter and more

[msmafra]

At the begining it was just to add -v and --version to check the current version of Hyprshot.", but decided to make more changes after. So now...

Making shellcheck happy adding and moving things to a main function, removing some deprecated things like backticks “cmd” in favor of "$(cmd)", putting variables declaration and attribution in separated lines, setting variables types when possible and other changes. Made some variables less verbose narrowing their captured values with jq.

New features:

1. Added the short and long arguments -v and --version to check the current version of Hyprshot;
2. -a, --annotate to call an annotation tool option that auto chooses between Satty (default) and Swappy;
3. --cursor to enable show cursor option option on the captured image*;
4. -p, --viewport to capture all screens at once (all monitors at once);
5. --no-clipboard take screenshot without copying it to the clipboard;
6. It will also choose between grim (default) and wayshot;

Mind you that at least currently wayshot has problems to capture all screens. (tested on Hyprland 0.48.0)

Probably helps with
#17
#25
#37
#66
#102

*at least on my machine, even without passing "-c" to grim it captures mouse cursors some times. I imagine is related to NVIDIA drivers and /or my Hyprland configuration related to NVIDIA.

Need some more diversity in testing. I tested mostly on my machine using Fedora Workstation 41 and a bit on CachyOS.

Added [Draft] to the title since it needs some testing and I'll make more changes.
