Support static image as preview

Render map image via [static api](https://tech.yandex.com/maps/doc/staticapi/1.x/dg/concepts/input_params-docpage/) Cases: - while loading API - javascript disabled (?) - support print mode in future (?)

Performance issues

- [x] Use GeoObjectCollection for Markers

Now this params calculated dynamically

- [x] [Map](https://tech.yandex.com/maps/doc/jsapi/2.1/ref/reference/Map-docpage/#event-actionbegin) - [x] [GeoObject](https://tech.yandex.com/maps/doc/jsapi/2.1/ref/reference/GeoObject-docpage/#event-balloonclose)
