feat: implement discord buttons

This commit introduces buttons to the rich presences.
The JSON structure would be like this:
```"buttons": [
    {
        "label": "Global Button1",
        "url": "https://url"
    },
    {
        "label": "Global Button2",
        "url": "https://url"
    }
]```
The buttons array can contain 2 elements as a maximum.
Like other parameters, the buttons can be implemented globally and in each state.
