Add markers & custom markers on Static API

[FlorianBurgevin]

Hello,

Today, with the Static API, we can only add features in geojson with the sdk.

Is it possible to add markers and custom markers like the documentation below
Static API category marker

Like pin-s+blue(lng-lat) or url-{myurl}(lng-lat)

Thank you

@FlorianBurgevin yes, I think new Marker and CustomMarker classes would be an important addition to the SDK.
