Support aeroway=helipad

[Slord6]

It would be great to have helipads mapped from OSM into Arma (example, wiki).

Arma has the following vanilla assets that could be used as variants for this:

• Helipad (Circle)
• Helipad (Civil)
• Helipad (Rescue)
• Helipad (Square)

Extended work to identify helipads in military vs civil areas vs hospitals and using the appropriate helipad could also be done, but isn't necessary for my use.

Thanks!
