Add support for right-to-left scripts

# Support Right To Left Text Use the mapbox-gl-rtl-text plugin to support right-to-left languages such as Arabic and Hebrew. By setting the `lazy` parameter to `true`, the plugin is only loaded when the map first encounters Hebrew or Arabic text. ## Demo ### Plain HTML You can find the live Demo on CodeSandbox [here](https://codesandbox.io/s/fjgq7?file=/v2/support-right-to-left-text.html). ```html Add support for right-to-left scripts
