v2: Updates to Inbound msg.notificationOverride Structure

[sstratoti]

From discussion in #6

it may make more sense to create an inbound msg object with a bit more depth in structure. This would be a breaking change for inbound messages.

Like:

msg.notificationOverride = {
    title: "dynamic title!",
    subtitle: "dynamic subtitle",
    message: "Battery is at 50%!! Replace it soon!",
    url: "/hacs",
    services: "my_phone, partners_phone, kids_phone",
    cameraEntity: "camera.my_back_yard",
    interruptionLevel: "time-sensitive",
    tag: "xyzTag",
    actions: [
        {
            title: "New action Title for action 1!",
            actionOutput:1,
            activationMode: "foreground",
            uri: "/example",
            textInputButtonTitle: "Reply",
            textInputPlaceholder: "Type here...",
            authenticationRequired: true,
            destructive: false,
            behavior: "default",
            icon: "mdi:alarm"
        },
        {
            title: "Another action title for action 2",
            actionOutput:3,
            activationMode: "background",
            uri: "/another-example",
            // Additional properties...
        }
        // Add more actions as needed
    ]
};
