Preset auto-loading based on the current activity

[luisbocanegra]

I already use org.kde.taskmanager to detect maximized/active window so it should be a matter of listing and linking presets to them in the presets auto-loading tab, then implement the detection and switch similar to existing ones.

For future reference here's an example of what presetAutoloading (https://github.com/luisbocanegra/plasma-panel-colorizer/blob/0b3fa70a665a69c073e3e20cdc05000e14251507/package/contents/config/main.xml#L40C15-L40C32) currently stores:

{
    "enabled": true,
    "maximized": "/home/luis/.config/panel-colorizer/presets/border",
    "touchingWindow": "/home/luis/.config/panel-colorizer/presets/border",
    "floating": "/home/luis/.config/panel-colorizer/presets/border",
    "normal": "/home/luis/.config/panel-colorizer/presets/border",
    "maximizedFilterByActive": true
}

Maybe activities could be added like this:

{
    "enabled": true,
    "maximized": "/home/luis/.config/panel-colorizer/presets/border",
    "touchingWindow": "/home/luis/.config/panel-colorizer/presets/border",
    "floating": "/home/luis/.config/panel-colorizer/presets/border",
    "normal": "/home/luis/.config/panel-colorizer/presets/border",
    "maximizedFilterByActive": true,
    "activity": {
        "activity-identifier-1": "/home/luis/.config/panel-colorizer/presets/border",
        "activity-identifier-2": "/home/luis/.config/panel-colorizer/presets/border"
    }
}
