Scrolls long text

## Source

https://github.com/rdkcentral/Lightning-UI-Components/blob/develop/packages/@lightningjs/ui-components/src/components/Marquee/Marquee.js

## Usage

This component takes in a string or a texture, applies a fade shader to the right, and scrolls the content in a loop.

```js
import { Marquee } from '@lightningjs/ui-components';

class Example extends lng.Component {
  static _template() {
    return {
      Marquee: {
        type: Marquee,
        w: 350,
        h: 50,
        title: {
          text: 'This is a scrolling Marquee component for long text',
          ...TYPESCALE.headline2,
          textColor: getHexColor(COLORS_TEXT.light),
          maxLines: 1
        },
        autoStart: true
      }
    };
  }
}
```
