Cursor style management

[varna]

Feature request

Hi, I want to control the cursor style, but the API seems to be not exposed? getCursor seems to be hardcoded into the layers. Docs are not very useful on this topic. The only piece of code that I found in git was:

<DeckGL
        getCursor={layers[1].getCursor.bind(layers[1])}
/>

Do I need to create my own mode or maybe a pull request to expose getCursor as a prop.
