feat(weather): add Buienradar provider (#4164)

This adds the weather provider Buienradar for the Netherlands and
Belgium without requiring an API key.

In MagicMirrorOrg/MagicMirror-Documentation#380 @plebcity shared his
implementation for the old browser-side architecture. I used it as a
reference to build this server-side implementation.

/>

### Example config

```js
		{
			module: "weather",
			position: "top_left",
			header: "Buienradar - Current",
			config: {
				weatherProvider: "buienradar",
				type: "current",
				locationId: 2747891
			}
		},
		{
			module: "weather",
			position: "top_right",
			header: "Buienradar - Forecast",
			config: {
				weatherProvider: "buienradar",
				type: "forecast",
				locationId: 2747891
			}
		},
		{
			module: "weather",
			position: "bottom_left",
			header: "Buienradar - Hourly",
			config: {
				weatherProvider: "buienradar",
				type: "hourly",
				locationId: 2747891
			}
		},
```

When this is accepted and merged I'll update the weather docs.
